Co-op Stop units from being shared

[djsatane]

I have asked for this over year ago but nothing came out of it as far as on developer side, I know that only thing they could easily add is an option where only host can buy but they never did. I know that a mod can be done where only host can buy but then everyone have to have the mod. Coop is basically single player game with more memory constrains and the game doesnt even really see multiple players as far as script goes.
