Lead up-- Past 2 days Warcraft has been acting very odd, getting a stupid amount of LUA errors even with the default blizzard UI. I therefore installed Bug Sack to not be spammed and continued on as usual. Today however when doing a LFR I would get LUA errors for showing the loot frame and therefore could not even need, greed, etc on any items.

I therefore decided to delete my WTF and Cache folder thinking something may have gone wrong in them. The game will now not remake the WTF folder and still spam's me with constant LUA errors, lagging out, etc. Any help would be much appreciated.
