[2023] Settler just stops

Hmm, that definitely sounds frustrating and I'm sorry you are experiencing that. I have a few fixes for this type of issue in the next update coming out soon. You might be able to fix it on your side, though. I would check to see if they are unable to reach some item that is in a cave system. That's something which was causing an issue in your version that I've fixed. They might also be hung up on trying to do a job that's unreachable, though, this isn't one I see too often.

Again, sorry that this is an issue for you. If it persists, you can send me the save file, and I can open it up to try and diagnose it on my side.
