On Retail, with v4.3(0225) installed. I am getting the following error. It started when I was doing the Primal Event daily and is now popping up every time I loot the essences, the items for the PE daily and on quest acceptance.

4x EMA/Modules/ItemUse.lua:629: attempt to call global 'GetContainerNumSlots' (a nil value)
