Not super helpful, but I am having the same problem. I have to uninstall all the terminals if I want anyone to actually look for food.

What kind of pawn is this “Defender #21”?

I'm also seeing lots of other mods in that stacktrace, so it's very likely you have conflicting mods.

Are you guys running mods that alter colonist or animal thinktree behavior, such as animals that “act” like humans?

Im any case, please follow this troubleshooting guide[gist.github.com] to narrow down the conflicting mods, then submit a bug report[github.com].

I have pawnmorpher installed, that I believe would make certain animals act as humans? I need to get my log uploaded...

Again, please follow the troubleshooting guide and narrow down the exact steps needed to reproduce the issue properly. A log by itself isn't particularly useful.

I'm closing this discussion, as proper troubleshooting and bug reporting guidelines were not followed.
