I noticed a couple things playing just now on a dedicated server:
1) Gibbed opponents still have the animation like they are un-gibbed (they lean up).
2) Sometimes when trying to throw airstrikes at a/s hints, they aren't switching the weaponbank. So they fire one bullet, reload, fire one bullet, etc. This is an old bug that's popped up again. Seems to happen every time on Ice on the doc run (near the truck at the tunnel).
3) When another human player taps out, As a med, I can see his corpse still and it has the revive hint on it (and on the radar)
EDIT: It seems to be hapenning with the bots too, so 1 and 3 are probably the same bug. I've posted a demo
here.
