3.2.2 EDITS :
The guides are always working, to fix the .MPQ wich aren't working you just have to follow the part 2°) but extract "CreatureDisplayInfo.dbc" from your patch-enGB-2.MPQ and not patch-enGB.MPQ as said in the Guide.
I don't understand those bugs about "race number", could you tell me wich race swap you are using ?
