Im not sure if somebody said it before, but Ive noticed that any immobilized tank (other vechicle probobly too but I didnt test it) will not show you which hexes are visible to its turret. If you rotate the turret it still highlights the area the tank is facing... not a serious bug but just wanted to make sure everybody knows
One other immobilized tank bug is that they can become "in cover". Now this means that while the tank can not move, its finding the best way to position itself within the hex which implies that it needs to move.

An old soldier but not yet a faded one.
OK, maybe just a bit faded.
Oh, I saw that "in cover" in the way, that crew is running around, bringing in branches, stones, logs, mud, sand, anything it can get, and masking and "duggging in" the vehicle with the stuff. Maybe unfastening gas canisters and throwing them somewhere far, far away.
oh that reminds me, the 'right click' on a target hex while having the immobilized tank selected bug is back in force, allowing you to change the facing of the immob'd tank.
