I have come across a couple of mods that I would like to try out. The only problem is they list UFO as being a problem for them and suggest AFT or EFF be used instead. Currently I use UFO and was looking for suggestions on how to swap it out for AFT or EFF. Or is this one of those changes that would require starting a new game. Thanks!

I've done this using the http://www.nexusmods.com/skyrim/mods/52363/? and Mod Organizer. MO minimizes the risk if it didn't work out. I've done this to at least 2 profiles and so far it worked for me. Here's the procedure I used:

1. Use MO and made a copy of the profile I want to switch from UFO to AFT.

2. Start the game using the new copy of the profile.

3. Dismiss all followers.

4. Find Tina the Firefly in Riverwood and stop the mod.

5. Make a new save. Quit.

6. Uninstall UFO.

7. Resort the loader with LOOT. Load game. Wait a bit and make a new save. Quit.

8. Open the last saved game in save game script cleaner.

9. Clean the file according to directions.

10. Load the game with cleaned save file. Make a new save file. Quit.

11. Install AFT. Resort with LOOT.

First off before using any save game cleaner is to back up your game saves as well what mods you are using. The cleaners can sometimes do to good of a job of cleaning in a bad way.

what companion mod are you looking to use? It might still work with UFO.

One of the mods I want to add is Sands of Time which lists UFO as being incompatible. So it is not a problem with companions exactly.
