I finally figured out how to run this mod; the flask in the top right. Great. So I start clicking around, but I cannot figure a single thing out. I don't know how to select a spell. I can seem to fire a single spell, and when I exited the Lab, my REAL game inventory had been erased. I CTRL-ALT DELETE quit the game and restart, but nope. All my stuff is gone. Run ruined, I guess.

How do I use this mod safely? Or at all?
