Whether it is related or not, cannot be sure, but just saw that on our tank-gunnery-range on our server, the ammo counter in the gunner view no longer counts down when shells are fired at all. Probably due to the fact it is set to unlimited ammo. So it not counting down at all might be a good thing, and it could be the change to the code that caused the flickering and missing updated numbers for the commander in multicrew bugs... I dunno ...
