So ever since I started playing again I've been constantly harassed by claims of not having any seeds for my plump helmets. What change is it that has led to this trend? It used to be that you'd never run out seeds once you planted a single mushroom (I guess it was pretty broken that way...). Is return rate of spawn now dependent on Plant skill or something, maybe?
You can build a well on an empty channel and bring water later. As for bringing the water and dealing with pressure: DIAGRAMS below

None of your images are working for me.
Dwarfs can now pick up several items of the same type ( only works for some categories whit generally small items, like seeds, gems, bars, trade goods )
So if you have 30 plump helmet seeds laying in the still after some brewing, they are all being picked up by one dwarf, where before they would be 30 different jobs.
If your planter at the same time wants to sow, you can get the no seed message, since not only are the seeds being picked up part of one task, but also the storage where those seeds are being stored will be considered "busy".
Overall this is a great chance, since it requires far less hauling. You just need to rearrange stockpiles slightly different. If you got a stockpile for each type of seed you want to farm, and each of those stockpiles having room for 2 seed bags ( no barrels ) Whit this set up it's very rare to get a "no seed" message.
