FOR THE PEOPLE GETTING STUCK AT BASE EVEN WITH "SPOT ONLY" CHECKED:
As I can see much people got the same problem with the bot not repairing on "spot only" even if you checked that. So let me explain how to not make it stay still with your useless 3rd hangar:
You got 3 hangars set up in the bot itself:
1. Your collecting hangar
2. Your sell hangar
3. Your revive/warp hangar
So...
Even if you have checked spot only, you HAVE TO set your revive hangar up aswell. So you have to click on "by hangar on 5-3 1-10 (hangar hall)" and set your 3rd hangar and put it underneath the fog in 5-3. Now you've done that you can just click back to "on a spot" and check "spot only".
Now the thing is when the bot sometimes get confused it changes to your revive hangar and warps your collecting hangar to it.
This is what Palavia told me
