Found an issue with the Focus Stone (Healslinger) that spawns in your inventory after casting "Gather Focus". I get a microfreeze (stutter) whenever it pops up in my inventory and when i consume it (The "Focus Stone" Item). When disabling Commoditystats the freezes stop occuring so it is 100% the issue with the addon. Probably because it is trying to get information about the item on the auction house i guess? it is soulbound anyway and marked as "Potion".
