My fishermen, despite having the fish cleaning labor, never ever get any mussels or pond turtles. When I type in region-pops list on DFHack, neither of them show up. They are both in the raws, which say 100% frequency and any ocean/lake/river, but I am unable to get them anywhere. I had this issue in a shrubland biome too, so it's not just the mountains. Before this version, I had no trouble at all getting shelled animals from any place, ever. What's more, they aren't being shown in region-pops list. In region-pops list-all, there are only around 14000 mussels and absolutely no oysters or pond turtles at all.

This has persisted across multiple downloads , multiple versions, and multiple saves. I think it has something to do with modding, but even when I fixed it so that nothing pops up on the errorlog, that still didn't fix it.
