Thanks to the diligent work of the forum goers in this thread: Fort-born creatures stay around baby-size an issue with the current release has been found that fortress-born (as in the creatures born in your fort during a current game) creatures and dorfs will stay at or around baby size for that creature. This leads to several issues:

• Dramatically reduce the amount of butcherable meat and other products from fort-born creatures.
• Dwarves (and custom civilization creatures) will be born at dramatically reduced size and will not be able to field weapons like hammers, maces, greatswords, and the like as effectively as they should.
• Blunt weapon damage (aside from unarmed strikes) will be drastically reduced by these smaller creatures when wielding weapons that deal blunt damage.
• The general combat effectiveness of warbeasts will be greatly reduced from their wild versions. If you ever wondered why your hoard of sabercats seems to be slaughtered every sieges... well their about the size of housecats, adorable, but not deadly

Here's just how big the differences between fort-born(native) and migrant dwarves are:

Checking all the peasants:

Name	Status	Blood count	Description
Ilon Aquastockade	Immigrant	5940	Corpulent
Edem Roughnessjails	Immigrant	6180	Average in size
Avuz Anathel	Native	505	Corpulent
Etru Gembrush	Native	482	Strapped with massive amounts of muscle and lard
Solon Yellrim	Native	397	Average in size
Stukos Shinbronze	Native	457	Thin and scrawny
Zuglar Windlash	Native	311	Average in size
Fikod Inkmartyred	Native	443	Short and muscular
Cerlo Claspedtwisted	Native	382	Muscular
Morul Armorabbey	Native	722	Tall and skinny
Ast Chainedtraded	Immigrant	4440	Short and just incredibly fat
Logem Paddlesavant	Native	721	Short with well-defined muscles
Melbil Amazedmirror	Immigrant	5700	Corpulent

There is, however, a definitely fortressborn miner with blood count of 6060 and a woodcutter with 5940. I could likely find more normal-sized native dwarves, though the majority are indeed on the small side. Looks like things are getting complex.

Also, a random incredibly skinny kid is 811, a sample of five dingos (all gigantic) ranges from 379 to 1305, one horse is 60000 (presumably the single mare I bought from a caravan a few years ago), while other ones ( mostly 16000 - 22000) are slightly larger than foals (9000-11000); all are gigantic or enormous.

Current proposed workarounds include:
teal = confirmed
yellow= pending
red = debunked

ajg1j12 - Looks like PeridexisErrant's latest version of the Lazy Newb Pack already has Kurik's script installed.

If you want to apply it to an existing installation, rather than switching over your saves, follow these steps:

Step by Step Guide

1. Install DF Hack, if it isn't already. 

2. Inside your DF install folder (the one with 'Dwarf Fortress.exe'), navigate to the folder \hack\scripts\fix

3. Inside the fix folder - Right-Click -> New -> Text Document

4. Name the new file growthbug.rb (Windows will probably throw an error here, warning against changing the file-name extension.  Click OK.)

5. Open the file in Notepad, or your favorite text editor.

6. Copy-paste the following into the file:

Code: [Select]

# growthbug  enable [#d|w|m] |disable|status|now|help
DAY = 1200

7. Save the file, and exit the editor.

8. Navigate back to your Dwarf Fortress install folder.

9.  Open the file "dfhack.init" (May be called "dfhack.init-example".  If so, rename it to "dfhack.init".) in notepad/text editor of choice.

10. Add the following to a new line anywhere in the file:

Code: [Select]

fix/growthbug enable
11. Save, exit, and you're done.  Start up Dwarf Fortress normally, and if everything is working properly you'll see the line "FixGrowth: Running" in the initial wall of text that the DF Hack window spits out.

Additional Notes:

Spoiler (click to show/hide)

- This will not affect the ability of fort-born creature to wear or equip armor or shields, only their ability to wield and use weapons (blunt weapon damage is significantly reduced as it depends on size of the creature)

- Smaller creatures suffer less fall damage than "normal"-sized creatures.

- Occasionally dwarves and creatures will be born at adult size OR more rarely reach their actual adult size as normal. What exactly causes this is still unknown.

- A bug report has been made and it is has been set to elevated priority

--- The cause of this whole issue appears to be:

In summary, it appears that unit growth is intended to be recalculated once per day (and offset by the time of day the creature was born), but there's a further restriction that it only does that check once every 10 ticks, so if the creature's birth time is not a multiple of 10 ticks, its size does not properly get updated.

[Sutremaine]

Idea: use a transformation syndrome on minidwarves, turning them into dwarves. May or may not need to be permanent, if it works.

[Black_Legion]

Idea: use a transformation syndrome on minidwarves, turning them into dwarves. May or may not need to be permanent, if it works.

If the reaction is permanent then it should make them the default adult size, assuming transformations always sets the creature to an adult version of the transformed into creature. This would require a regen and necessary interaction tags in the civ file which is a drawback. We should probably use some science on that, though to my knowledge no one has ever done transforming reactions on children.

[fricy]

You are onto something with transformations:
Tested with Masterworks mod 2.h - Heal nearby pet reaction in the Warkennels & Transform into Armok's ward in the temple.

Drake: before age 2, blood  562, after: age 26!, 14980
Dwarf before: age 13, blood: 864, after: age 3!, blood 2270

As for how permanent it is: The transformation seems to screw around with the birth year to (by?) a negative value (wtf??). I found two creatures in my fort that have neg. birth year, (I ran this reaction a few times before, so I assume these were  the ones healed by it) one of them normal size, the other micro size. So that's 3 out 4 transformations that fixed a creature.

So could you stop a animal/dwarf from dying of old age with that?

Oh, wow... I had no idea this was happening. Do you guys know how long this has been going on? :S

Sure, there's even a workshop that does exactly that. I couldn't test that reaction though, because I forgot to fix a bug with it, and the building decontructed...

The thing is, I don't even know how these transformations are supposed to work, and is the age thingy intentional, or some quirk.We nee some modders here...

[Black_Legion]

Oh, wow... I had no idea this was happening. Do you guys know how long this has been going on? :S

From the thread this issue seemingly came up in the creature/body rewrites of the .31+ era. The in-depth butchery analysis of things like the mermaid farm of the .40d era didn't show any of these findings. Thankfully a bug report has been made in the tracker and it has been given elevated priority.

That's good that some of the transformation interactions appear to help this issue.

Here are some of the findings in the original thread that helped find the issue, these are just a comparison between migrant and fort-born(native) dwarves blood_max sizes (indicates the overall size of the creature):

Checking all the peasants:

Name	Status	Blood count	Description
Ilon Aquastockade	Immigrant	5940	Corpulent
Edem Roughnessjails	Immigrant	6180	Average in size
Avuz Anathel	Native	505	Corpulent
Etru Gembrush	Native	482	Strapped with massive amounts of muscle and lard
Solon Yellrim	Native	397	Average in size
Stukos Shinbronze	Native	457	Thin and scrawny
Zuglar Windlash	Native	311	Average in size
Fikod Inkmartyred	Native	443	Short and muscular
Cerlo Claspedtwisted	Native	382	Muscular
Morul Armorabbey	Native	722	Tall and skinny
Ast Chainedtraded	Immigrant	4440	Short and just incredibly fat
Logem Paddlesavant	Native	721	Short with well-defined muscles
Melbil Amazedmirror	Immigrant	5700	Corpulent

There is, however, a definitely fortressborn miner with blood count of 6060 and a woodcutter with 5940. I could likely find more normal-sized native dwarves, though the majority are indeed on the small side. Looks like things are getting complex.

Also, a random incredibly skinny kid is 811, a sample of five dingos (all gigantic) ranges from 379 to 1305, one horse is 60000 (presumably the single mare I bought from a caravan a few years ago), while other ones ( mostly 16000 - 22000) are slightly larger than foals (9000-11000); all are gigantic or enormous.

It's amazing to see the sheer difference in size between migrant and fort-born citizens.

[Hugo_The_Dwarf]

I wonder with this age breaker (in some cases i've had a creature rapidly age through transformation) I believe it's an issue with different MAX_AGE settings, imagin a dog that lives a max of 10-20 years, lets say 10 is the max (for easy figuring) and a dwarf is 100-150 (not the actual data in the raws, just easy figuring)

Now lets round the dwarf max age down to 100 and say the dog is 5 years old (half way)
would say transforming it to a dwarf create a 50 year old dwarf?

As I've done a little bit of testing and found that even a temp transformation to an ageless entity (Dwarf to Bronze Colossi and back) seems to drastically age the subject (in the few tests I've done) however some cases are that perhaps like MW age is thrown into reverse. If I can get this age breaker to work as I want, I could have a method of growing my own armies instantly. instead of waiting a min of 1 year (the bare least for the CHILD/BABY tags)

time to break the science out and hit up adventure mode.

[Toxicshadow]

Drake: before age 2, blood  562, after: age 26!, 14980

I didn't know Drakes live to be ~403,291,461,100,000,000,000,000,000 .-. That's also 4.032914611 * 10^26, or 26!.

Nevertheless, PTW, interesting stuffs.
