There is a bug with the split item. When one of the clones crashes, the screen of the spectators freezes until next round.
The room settings are: FFA or TEAM, 23 items (except darkness and closing wall). It always happens so it is easy to recreate but too lazy to take screens of it.
I'm using flash projector version 13 but people with browser or the newest version of projector got the same bug.
