Figured out the problem!
Thanks guys

Hi there thanks
Original works fine.
You get the people out on the street and can talk to Lisa and Apu in their buildings, but every mission I load, eg, level 2 mission 1, there's no Milhouse to talk to. The only thing that shows on the radar is the dollar sign, phone booths and cars.

Hi there, I'm new to all of this, what is the vanilla game? Thanks
