Don't really understand why being a gm and a mentor comes into play here. If the mentor didn't get punished because they had mentor privileges then sure. But if anything this proves the opposite.

I've been a mentor while being a gm and while not being a gm. I have always been willing to throw any team under the bus if I thought they were doing something sketchy. Never had to for this though.

Would love to see a real situation where this was an issue if it exists though. From my experience the gm mentors are the ones that the the first gens find the most helpful because they are the ones who care the most. Is what it is
