Also getting no tooltips in my OneBag and only this error:
Error: attempt to index local 'self' (a nil value) File: Interface\FrameXML\ContainerFrame.lua Line: 602 Count: 1
tried to fix line 57 as mentioned earlier, but didnt work out... :( any ideas?
This isn't caused by OneBag, but by another addon - try grabbing BugSack/BugSwatter or another addon that captures the addon which called the function as well to figure out which addons are doing it. As of right now I know that MonkeyQuest, Lootlink (although the most recent is fixed?), and ItemRack are causing it.
Unfortunately with regards to the bank errors I'm having the same issues :(
