No, everything is fine. I launched the game, entered the world with this mod (and a hundred others), gave levels to my weapons, no crashes or anything else. Most likely, your game is broken by another mod (even if you think "I played with this mod 100 times and everything was fine" - they can release an unstable update. There is also a possibility that my mod along with another one is breaking the game, but... it definitely won't break anything at the game loading stage, since it is already enabled in the world.
