I had a problem with interacting to NPCs or any objects after using this. I only used the no slope and no clip feature to test it out and later I reverted it by closing the game and opening the hack loader with all features unchecked (figured this would revert the changed files into originals). It did remove all the hack features but now I can't interact with any NPCs or any objects. My interact key is the same.
Note: I do use the turban mod from ToraTenshi which does deal with interacting with NPC/objects. Maybe this somehow interfered?
So I decided to delete the BLGame.u file, did steam verify file integrity to recover it and it also changed all the ini tweaks including turban. I changed back the ini tweaks and turban mod and now it's working.
