There are a few posts around the forum about this, but I cannot find any official response or statement on the issue, whether it's a bug or an intended change.
If your bank is full and contains, say, 50 Iron Ore, and you attempt to deposit 1 Iron Ore into your bank, it will tell you that your bank is full and reject the deposit. This is different from how it used to work (before Thieves Guild specifically, according to other posts), and greatly exacerbates any inventory management issues one might have.
I'd greatly appreciate simply knowing if this is a bug and is being looked into, or if it was an intended change. I'm really hoping it's the former, but any answer would be, again, greatly appreciated.
