When i click on a bank it doesn't do anything. I can open my bank window through the backpack tab, but I can't withdraw anything from that window. When I disable Bagnon the bank works just fine. Guild Bank, Storage, and Backpack have no problems.

It was WeakAuras2 as someone else has stated. I don't use WA2 so I ignored that theory, but i had it installed for some reason.

I do not have weak auras and I can not access banks with bagnon turned on :/
