Are the Imperial version and the non-Imperial versions compatible in multiplayer campaign?

My friend is using the Imperial version(which adds 10 units) and I am using the non-Imperial version on the Europeon multiplayer campaign map.
When he ends his turn, I crash to desktop.

Anyone have an explanation?

probably a bad save, or the AI doing a wrong move, it happens, but yes those 2 versions are compatible with each other

But you both dont have the 10 extra units in MPC.

the normal version won't build those, but the files are there
