Aye, I couldn't move my vet 1 jeep to unassigned so I had to decommission it to move it to another screen
(not that a vet 1 jeep is crippling, but you get the idea)
I did some more testing, the window for actually dropping the unit in the unassigned section is much smaller then the visual size of the box. Its more like 1/4 of the way from the top,and potentially stops at the 1/2 mark. Remember when you would remove all your items from unassigned before, the box shrinks to miniscule amounts, and when you try to p ut them back in you have to hit the box EXACTLY for it to pop back up.
its doing that again, but we have no color representation to actually see where the box is atm.
imo the box should have a minimum size requirement to stop it from minimizing to useless proportions.
