Fuck it, I'll just post it here.
Here's all the info you need to generate decay-free worlds.

Anyone tried to delete the age folder from the save folder?
EDIT: Just tried with a test save. It creates it again, identical, so it seems the seed (and parameters?) are already set, or maybe part of the book or part of... something.
Yeah, you'll have to delete the relevent agedata_##.dat from \saves\SAVENAME\data\ as well as the dimension folder.
Awesome! Ack, can't believe I missed that folder, that was exactly what I was looking for. Just assumed the data folder held Vanilla data.
Then again, I don't mind keeping the "Age" data if I'm no longer going to go there and it's not using up any resources, since the folder stays gone if I never revisit (being careful since all linking books there will be gone also). Besides, the age ID is correlative so there's no hope anyway of "reusing" the age ID, unless I wanted to resort all other age IDs. That would be messy.
BTW, great info on the source code. {EDIT: Just realized one major source of instability, a lot of these Random Ages have both Flat AND Caveworld. I was wondering why it didn't look "cavey", it was because Flat was overriding it (and adding decay, probably
)}
EDIT2: Spoiler alert: a game started in Creative mode automatically generates complete notebooks.
Playing technic+mystcraft; damn getting Thaumcraft crystals is easy. Craft a musket with bayonet, a bunch of bullets, and suddenly all those high-aura, high number of living crystal spawning eras are great. Click... Click... BLAM! *collects crystal* Click... Click.... BLAM! *collects crystal* Click... Click... BLAM! *collects crystal*
Also, for the record, musket with bayonet is the best thing ever.
Wha? musket, why would you use a musket...
Ah, "living" crystals. Gotcha. Not a bad idea, think I'm going to add the Extra Weapons (or however it was called) mod to my MultiMC instance. Too bad the author hasn't figured out enchants yet (at least for the melee weapons) since every other modder seems to have.
