XD gets pissed at people trying to enter the end and force rejects everyone from the server, unfortunately it ejects them right into reincarnation.
Cue mass panic.
Cue Philza panic, as the ejection just sent him to another server due to his connection to Death.
Cue even more annoyance, when eh finds out all the servers are frozen due to XD by accident and he has to retrieve everyone from the DreamSMP server reincarnations to fix it.
