All the people who've got in, myself included, we're in residential zones when it crashed or when they logged off. If you try to leave them you will get the loading screen issue.

There was also a rollback of at least one increment (15s) as I'd deciphered a map prior to the crash and it's now back in the bottle. It could be longer than one increment but I have no way to check. If you got a loot drop or completed something just before the crash you may want to check the status of it to see if you completed or still possess the item.
