All animations should be immediately interruptable. A reload animation whilst prone followed by a roll left/right command should result in an immediate roll with the reload being interrupted and a probability of the magazine being dropped - later on when you guys implement those kind of social aspects.
Same goes for changing stance during reload.
Because noone stops dead to reload. It makes no sense. It's a coding problem that doesn't make sense to reflect ingame.
Same goes for healing animations, repairing animations, any animation. Just add interrupts to the loop.
