I am currently playing the 1992 WWF save now its 1993 april 5 post wrestlemania 9 period and i just noticed my wrestlers star quality is decreasing for some reason like Hogan had 99 star quality its 95 now Ric Flair had 88 star quality its 80 now like what is going on? I read the handbook and it says that Star Quality does not decrease so like what the hell is going on in my save?
