You need to check the readme files more carefully to avoid things like these: 1. The readme file for the FOIP compatibility patch for MMM-FWE clearly says that you must deactivate these components, since they are integrated in FWE: Natural Selection, Tougher Traders and Zones Respawn. 2. The readme for FWE tells you to pick one and ONLY one from each of these pairs: Optional VATS Halftime - OR - Optional VATS Realtime ;; Optional Restore Tracers (automatics only) - OR - Optional Restore Tracers. For example, you either want to restore tracers for all weapons, or you want to restore them for automatics only, so pick one and kill the other. The same for VATS, since you obviously cannot have it running at both halftime and realtime simultaneously. 3. The readme for the FOIP tells you how to set your load order. For example, it tells you that weather mods should be loading at the bottom of your load order. To fix this I recommend you just get and install BOSS, and run that to sort your order for you. When you have fixed those installation errors, try to deactivating these components: EVE - FWE Master Release.esp EVE - FWE Master Release (Follower Enhanced).esp EVE Anchorage - FWE DLC Anchorage.esp After you have done all that, you should then get and run FO3edit to make a merged patch. Then test the game and let us know how it went.
