So I have the mod set up, tweaks added. Started up the game, great everything's working no errors etc. But If I go to the Slaver's Guild it changes the background Maple is there, but the options on the left remain the same as if I were just out in town. so "visit mages tower, visit slaver's guild etc with the slaver's guild background. Not sure if I've some how fucked this up, or what, but you have an answer I'm all ears. This is what pops up if I click on the slaver's guild. 
The most likely cause is that you applied the AricsExpansion mod through the mod system. This mod comes pre-installed and installing it again will break it. In the best case, all you need to do is deselect the mod and re-apply. In the worst case, you will need to extract a new copy of the modified Strive program folder.
