Hi Haplo,

i got an issue with hauler bot. All was working perfectly then i got a major issue. Hauler bot doesn't work anymore and are wandering and instead i've this error spamming. IIRC, it remain at the update of "Federation" mod (faction whitch include some object in this last update).
I've enhanced hauling too and give me that brick, but desactivate them doesn't solve the problem.
Any Idea?
