Texture/Mesh Messes Up When I Make Vertex Groups for Rigging?

Hey guys, Im having a little trouble with my model when Im creating vertex groups for rigging. What happened was at some point during my vertex grouping my texture went from fine to all sorts of messed up but only in one spot and it wasnt even the spot i was grouping. When I switched back to UV Editor to see what was going on, nothing had changed and according the the UV Wrapping, everything was in its proper place and it SHOULD be displaying properly. I did a couple of google searches and found a couple of solutions that worked for other people but not for my instance. Does anyone have any idea whats going on and how I can fix it? I do have a earlier backup of the model that displays fine but its just before I started vertex grouping but I was hoping I wouldnt have to go back that far.
