I had a trader come by, giving me two wall gargoyles for some corn i think. i went straight away to place them on a cliffside, before any heartlings picked them up and placed them in storage.
One of them was placed correctly, the other one was replaced by a chair… see picture.
Another thing i have experienced, is moving filled crates, gets replaced with new empty crates from the stockpile, and the original that was intended to be moved stays at the old location.
here is a link to the savefile. i hope i did it so it can be downloaded, otherwise let me know.
