T-pose when you got 0 stamina(hp)? This is not bug. Its just no animation for waiting while somebody going restrain MC.
About bullet tracer its just for debug, I'll chande it into something suitable, Also I know about buggy shooting system (weapon start shoot far away when target is too close) I gonna rework shooting code in 0.0.0.4 version.
T-pose when you shoot too close? Can't find it right now, trying to shoot as close as possible but no t-pose. Maybe your stamina dropped to knocked down state when you did that?
