For some reason Whenever i play as General Granger in the challenge mode it crashes every time i beat Dr.Thrax no matter what i do.

(This crash only happens to granger and none of the other generals after i fixed the game.)

(Nevermind , turns out the crash happens when there is a supply plane on the map , so selling all your supply drops and making sure no supply planes are still on the map fixes this.)

My Alexander challenge campaign crashes every time I win against Granger. I saved it a minute before winning and tested it 4 or 5 times and always crashes. I sold all my supply drops and destroyed his drops too but it still crashes. Any advice?
