I've run into a serious issue where my entire fortress is starting to starve and doesn't appear to eat any food from the stockpiles - I noticed while I was on the surface Roclets spend a lot of time running around with 'No Job' chasing vermin, and now that I've moved down into the rock layer they are starving. They'll happily drink booze, but the only ones who aren't hungry are the occasional Roclet hauling wood or something else back down, who seem to detour to the animal pens and hunt the vermin spawned by the bigger birds.

I tested a new world with the same mod list, and the same issue occurs - a dwarven fort in the same world does not have the same issue, so I'm thinking it could be the tag that makes them chase vermin also prevents them from eating normally?
