If a Heavy dumbfires a rocket, and then dies before the rocket hits something, the rocket will persist for several seconds at its 'impact location' before finally exploding, rather than exploding on impact immediately. This occurs regardless of graphical settings (low and ultra can get this bug, so it's not tied to graphical settings). Incidentally, staring at the 'stuck' rocket from up close, basically nukes the framerate on all but the most powerful hardware.
