Trying to download mob rule 2.0 installer leads to it downloading imperial glory installer.

Yeah, I just noticed the same thing. And it really is Imperial Glory, it's not just a misnamed installer.

Grrr, I downloaded Sacred Gold only a couple of days ago.
I'm reaching a point where I to enter this thread hoping to see none of my games in anyone's list of updated ones.

I know that feeling thankfully GOG is putting an end to it soon.
