PC/NA - Win 8.1 - The game runs fine for the most part. This issue began about 24 hrs before the cwc update.
When I go to a banker, the option to select guild store and guild bank are gone. Also when I go to any guild trader (not just mine) the only option is "goodbye." Despite not being able to view any listings from any trader, I have sold a few items that I had previously listed, so everything from that side must be working fine.
The first thing I did was disable all addons. - That didn't help, but I'm leaving them all off until this is resolved.
Then I found this advice from the knowledge base:
Type "/reloadui" in the chatbox, for graphics or user-interface issues.
Type "/camp" in the chatbox to log out and wait 15 minutes before logging back in to perform a soft-reset. This will clear out the cache and allow the game to load properly.
I gave that a shot, but it didn't help. Please let me know the next step in getting this resolved.
