Been leveling alts with timewalking dungeons and today they aren’t there. Checked on multiple characters and they are no longer listed in the group finder. The quest to complete 5 is still available as I accepted it before trying to queue…
The weekly events end an hour before weekly reset now with the time change (6am Pacific). It was not noticeable before since the maintenance started when the events ended. You can check the event times on the in-game calendar, but check back when maintenance is over and it should be available. Next week it will swap to WOLK Timewalking before going back to Classic.
