We just went into the alpha Overseer bossfight. When it was on half health, it just turned into a little metal ball that started projecting planets and a big bubble started to come up. After the bubble was completely closed the screen turned totally white, the only thing we could see were the names above the players. we tried to restart the game one by one but the every time someone spawned back into the game the same thing happened again. so we all left the server at the same time and respawned into the game -> we all died.
