- /kill in duel stops the duel completely?
- if the player you try to invite is in front of the skulls pickup thing, then they're not in the duel arena and you can't invite them.
- skulls pickup randomly disappears if you cancel the duel
- after the /kill in duel bug it still thinks you're in the duel, so you can't invite anyone else
- exiting the duel spectate mode sometimes randomly teleports you to 0.0, 0.0, 0.0
- sometimes rotate overview rotates between duel arenas, not camera angles of the current duel arena (or is this meant to happen?)
