Acutally I solve my little problem thanks to a suggestion made by UnderGod which seem to make all my other problems find solutions to themselves. My idea work and I'm up and running. My shifter mod has it's own script running, my meltdown (which I haven't tested yet) will have it's own scripts running and TRPG is running deus pack just fine with no interference from other scripts. Thanks for all your suggestions.
-RPG-SecretAgnt, sorry I wasn't who you thought I was. Sorry to had disappointed you, was he a friend who left or something. You don't have to tell me if you don't want to.
