As the pre-patch event ended today it seems some of its loot has started acting up!
Players have been reporting all of their pre-patch gear turning into Soulbound items. This is particularly problematic for those players that stored it all in the Warbank or on a bank alt so they could distribute it around their characters later. To make matters worse, after becoming Soulbound, some players even report the gear disappearing out of the Warbank alltogether!
Luckily Blizzard are aware of the issue and it’s being looked into.
I’m not going to move this one to bugs because there are already a few threads on this going over there.
This has been reported up – and is being looked into.
