My chat account is getting auto re-parrented to my highest rep account on the SE network (U&L) no matter what I manually set it to. As I have no diamond there, I have lost rights to moderator stuff in chat.
Right before mine happened, I was talking to a user who a user who had dropped out of the mod room we were in. We couldn't figure out how to fix his chat parent account. Five minutes later, my account broke too.
