I haven't been able to identify exactly when this happens. But the map will crash during a duel. It doesn't happen right away, but as the game goes on, it will crash after a duel. What I've witnessed is the player will die, but then almost instantly respawn and start attacking. Then the duel will end imeaditely after, the player will get respawned to where their opponent was last at.. and the game will then just crash.
