Patched Bagnon with v7.2.7 this morning, closed out WoW entirely. Reopened WoW, went to my bank toon, and tried to open the guild bank. Bank will not open. Received the error message below.

Did you try downloading the following zipped up fix for this from the Project Issue #585:

Bagnon_73_Ready.zip

Thank you - this patch fixed the issue. Both bank toons can access and display the guild bank correctly and search works as well. I had used the previous patch to no avail. Thanks, again.
