Icon bar question, really odd thing happening

[zaradann]

Icon bar, 1st icon has Shadowscream Scroll of Effectiveness in it, been in for a month or two, working fine. Last week I ran out of the scrolls, bought more put them in the same slot, same backpack they were in. Click icon on Icon bar, get the message, "You may only use items from your inventory". Odd, so grabbed the stack to my standard hot bars, works fine. Odd.

Used Unified to clear that Icon bar icon, logged, added it back, logged, Icon bar icon is now back, still same error. Looks like I just ran out of Shadowscream Scroll of Talent also, buying a couple on broker. Placed in bags and it works great.

So, after raid I will clear the slot again, and try adding to an empty slot to test
