1: It's hosted at my house, and I feel a bit odd about it, seeing as I invited them.

2: Do you think "Let it be and change it all back later" is ok? I kind of want to address this now, but don't know how. It was mentioned in a fight that the robot couldn't be hit except with a natural 20, and I don't want to take over and re-instate the AC14 when the group has become dependant on the robots. That also has the possibility to level the mutant up a few times depending on how long she DMs for.

3: I want to talk it over OOC, I just don't know how to deal with it, or what order to tackle it in.

I'm going to ask on facebook where the alternate experience chart is, and go from there I think.
