Since the last update, the guild bank sort is broken, it now sorts from tab 1 and not from the currently selected tab as it used to do. This is using a lot of memory and even if you close the guild bank the next time it's opened it restarts the sort, and the only way to stop it is to log out and back in.

Also noticed that you can't shift/click to select a different amount in the bank. you have to take all the select in your bag and put the rest back. Just a small annoyance.
