First off, I installed this mod understanding that there are a lot of bugs, don't read this like I'm on a rant or anything :)

When I make the tank form a caravan or undraft it after drafting it, it goes auto-pilot and just starts hauling things in my colony until I deactivate it. I basically can't use it for anything but hauling stuff in my colony, or fighting in my colony. I've been searching for others having the same issue, but I can't find anything.

I have the Misc. Robots mod installed, so perhaps the hauling bot AI is corrupting it? Just a blind guess, I know next to nothing about mod creation and programming.

Also, sometimes my colonists become uncontrolled and part of another faction after they leave the tank. Seems like other people have this bug, though.
