Ok... I'm completly unaware of this bug. When the screen is not filling an error log should be created. Can you tell me what the error log shows?

Do i need to do something for that error log to show or is it written to a log somewhere?
Found a workaround tho so its not gamebreaking any longer.
If I simply recall all bots, caravan creation works, and when I transferred one of two of my hauling stations to my new base it seems that I do not even have to do that any longer.

So, Im glad for your help but Im fairly sure this has something to do with my rather expanded mod list where this mod just happens to trigger something and with this workaround I think im good :)

For anyone else who might have this issue - If you have two or more of the same type of bot this issue triggers. What I found is that if I give the bots a unique name thru the robots tab I will not have this issue.

I had this problem for weeks, and it wasn't until about 3 days ago that I figured that out as well. Lost great playthroughs because I abandoned after I couldn't figure out what was going wrong. Now I just have to recall all my bots, not even dismantle them, but just recall and everything works fine.

I had finally got sick of having this problem, and spent 2 hours debugging my game trying to find the problem. Destroyed one section of base, tested to see if it worked, and would move on until I found the location of whatever it was that was causing problems, then I'd reload, and go item by item in that area. When I discovered it was the robots I was thrilled, because there was such an easy fix. I haven't tried renaming them, but I will do that next time.

Confirmed that this issue is resolved either by recalling all the robots or just renaming them. The error that seems to pop up is a graphic error where the trade caravan screen is shifted and generates a blank screen while dev console spawns endless GUI error.

I also had this problem and have deleted like 16 games before figuring it out, thank you all for the fix idas I pray they work I have to start a new colony again and test it out .
