Thanks to the weirdness that is BOSS, I have to restart my load order. However, my save is safe. If anyone could recommend me some Stealth\Magic mods, that'd be great. I'm looking for anything that boost Gameplay and any good Quests. I already have RL, DR, and OOO, and am reinstalling MMM (now that my Oblivion.exe is < 500K, I can probably use MMM).

What do you mean? BOSS does not touch your saves... BOSS corrects your load order. If you need help getting MMM+OOO to work, see the link at the bottom of this page: http://sites.google.com/site/oblivionpoinfo/walkthroughs/baininstallguide. See Part V of that guide for suggestions for magic and stealth mods. That guide is for BAIN, so if you are using OBMM, ignore the "you have to download BAIN-ready packages" stuff. If you want to convert to BAIN, follow that guide.

I inadvertently make everything to complex.
