Thanks for reporting these bugs! I will take a look tonight to see what I can do about these.
I haven’t looked at the Sol Standard code for a while so my memory might be off, but I believe under the hood it changes to the Wander routine if they can’t fulfill it, but it should then trigger immediately so it effectively just makes them wander. Getting control over the creeps is a weird scenario. It might not be a quick fix since it may be tricky to reproduce. I very much appreciate the video you included and the detailed report!
I’ll let you know when I have fixes for these.
