You are COMPLETELY correct! Thank you very much!
I had to search for what you were trying to say, so let me clarify: I missed the mouseover which showed me if I had that item on any other toons, guild banks, banks, etc. That stopped working, until now. Here is how to get it to work again:
Go to Interface/Addons and open the options next to Altoholic. Scroll down and select the "Tooltip" section. From there, UNCHECK the first option, which is "Show Item Source".
This is just to get us by until the update. I'm going to try to donate very soon. It wouldn't be much, times are very hard right now. I don't even have my expac yet....but I'll see what I can do. Altoholic does SO much for us. Thank you for this addon.
