Darkfall Unholy Wars to test the latest patch got an unexpected surprise not listed in the patch notes. Sure, everyone was expecting new warships and combat changes, but everyone was not expecting to log in as an administrator. That was apparently true of every single player logging in immediately after the patch, prompting immediate forum speculation that a rollback was imminent.
According to an official statement, the addition of the admin tag was purely a display glitch and no players actually had access to admin powers. Whether that's accurate or it's simply a matter of no players figuring out the admin commands before the issue was fixed is slightly ambiguous. Either way, the patch is now live and everyone can enjoy it, but not everyone can enjoy the sort of unfettered PvP you'd find in a world of admins -- which is probably a good thing.
