Realm name: WorstRealm2
Registered to: unerds_
Issue: A bunch of players attempted to activate the Nether Reactor - apparently, all their clients crashed (maybe one didn't) - now, nobody can join it.
I attempted this morning - no go... I then proceeded to attempt to join a different realm with no issue.
so it seems like something is wrong with that specific realm.
this issue has been resolved
