There's a small, but slightly annoying bug I have come across. When you open your backpack inventory screens by clicking on the journal, I've noticed that when you click on an item, you cannot see what it looks like. You can go to your bank at your house and it will work, and it will also work in a store, but not if you look at items in your journal. The only items I can see are the ones I currently have equipped. (I can see the spell cards just fine)
If I remember correctly, this used to work a long time ago, so I'm guessing something went wrong during one of the updates.
I realize this is not an urgent "It needs fixed now!" bug, but I just thought I would bring it up as it can be a bit annoying.
