I should've called it, the "Anti-Mod" or something like that. Note that, it is not designed to be used with all of the mods, like those add new classes, or new pets, or skills, spells, etc... Check below as to what might happen:

-Especially if you are using a new class, your save is always dependant on that mod.
-Pets, pets can be "tricked", by feeding fish.
-Skills, spells... Be sure to remove them & get a complete respec, or you'll lose your skill points.
-Inventory mods, well anything extra will be gone (in Bigger Inventory's case, all gem tabs for example)

too bad this is not permenant. But is great if you require 2 or more mods.
