When an actor without a Pain state is hit with a ForcePain missile (+ForcePain in DECORATE, bForcePain in VavoomC), it will instantly disappear without any sound or corpse. This will happen even if the actor is an obstacle that can be destroyed and normal

Fixed the states problem, if no Pain state is present, the flag doesn't do anything. As for 0 damage projectiles, I think it should make actors go into Pain state, I'll look into it ASAP.

Fixed both problems.
