[Question] Crashing WoW, need help fixing it

[Breakdawn]

Hello MMOwned.

Some of you might read my thread on the advanced editing forum, and know what i'm working on.

Well we hit a huge wall, we wanted to keep some of the old content to make players feel that it isn't completely new, that they still have some knowledge of the zones their walking in.

But when we tried to edit a few details on old content (Like elwynn forest). It worked fine in NoggIt

But when we added it to our MPQ file, it crashed our wow evertime we entered the area.


So now my question is, Does anyone know what causes this? and how do we fix it? It's important, or we might need to redo the entire concept, and that will extend our schedule for way too long.
