Came back and updated all my mods accordingly in terms of compatibility with the mods I have. This Mod offers 26 new levels starting in TB-Mode, each with a goal to reach, making matches more eventful and of course new weapons, armors, and lots.
If you mess up the game by installing every mod you can find, no memory management will help you.
so yes, it safe (like the chance you got fault condom when you buy one). Well, I got no problems using Buffout.
