Rate of fire question

[Imp]

Not noticed this but since the patch have noticed several instances of the following using different units from different OOBs
Infantry units firing RPGs at armour targets in my turn at least don't fire the last shot but it counts down.
Using standard fire with the F key not selecting a weapon.
All shot counts decrease by 1 & other weapon slots fire but the RPG does not fire
Checked it had HEAT ammo available.
Movement - can say has happened with stationary firer, may have moved last turn though.
Suppression - think this MIGHT be a factor as seem to remember most were lightly suppressed as in 12 or less.
Cant see it being the shot is not good enough to take has happened once the unit has already taken 2 shots at the same target.

If this happens to anyone or me again can you post a save game
