Bug-Colonists stuck wandering

Hello all. I'm experiencing a rather annoying bug right now. A while ago, I constructed a shuttle, and it worked fine. Recently, I loaded some colonists into it and tried to go on a raid, but when I clicked "Drop in Center" or "Drop at Edge", nothing happened. (The shuttle was fully fueled) After a while I gave up and unloaded it. Most of my colonists went back to normal but three of them went into a wander state. The little clock icon doesn't show up on their portrait, their current activity is just stuck on wandering, even if there is work for them to do and even if it isn't time for work. The only time they stop wandering is to eat. They won't work, won't go to sleep until exhaustion forces them to collapse, and won't do recreation or interact with other pawns. I can force them to work manually but that's really annoying because I have to constantly micromanage them. I restarted my game a few times, ensured their allowed area was unrestricted, and I even deconstructed and rebuilt the shuttle, but It's still not working. Has anybody else experienced this? Does anyone know how to fix it?
