I'm not sure how to reproduce this bug. After ending a previous match with self-destruct (most probably), or ending it in the Moon (2nd nuke, less probably), in the next matches, the main player's HP displayed in the hud is 0 (when in reality is full HP) untill the player is damaged and it shows the current damage. This keeps happening untill the player exits the game.
I forgot to take a screenshot when it happened (and I need permission to post someone else's screenshot @@).
