Just had a crash very shortly after a coati made off with a wooden minecart.
That could be coincidental, but can't think of anything else unusual going on. Am only in summer of first year of this gnome settlement, and shaking out the druid functions more than I have so far, so all stock buildings except for those. Had up up the animal treatment building and the advanced animal training building not long before, but only treated some wounded dingos and wolves, and didn't see any issues there, and had done nothing with advanced training yet. Have been chasing down wild animals to tame along with getting the basic setup and a pallisade up.
This is the 5.10 version. No tweaks outside stuff in the configuration manager (active civs, etc.)
