I know there is a mod already by Neder over on Mod the Sims 2, however, the mod for no relationship with the host does not work. The others work perfectly fine. Unfortunately, my sims still get the host to pop up on their relationship panel and I've already done many things such as not putting the file in double folders. (I have my folders organized by mods.) It just simply refuses to work. I have the Sims 2 Complete Collection so all EPs/SPs, etc.
