Have anyone ever met this glitch? I couldn't reproduce this, but once a Lost Soul in Doom2 became completely invincible, no instant ranged weapon (pistol, shotgun) could hit it (bullets hit a wall beyond), missiles could, but they did not seem to do any damage. Even BFG shot didn't.

If a lost soul hits something while its in its death state, it will be reset to its spawn state and you will have a lost soul running around with no health... Fun yet annoying Theres your bug. Nothing surious.

I added an extra check so hopefully this won't happen again.
