Hi Sato-kun! This mod is really great!
I created an account just to reply this post.
I believe that in most cases, the causes of incompatibility are some effects, buildings or even units. I was testing some factions in multiplayer and I did finish a few games, but if I play with USA Experimental, for example, their plasma defenses are responsable for the lost of syncronization (test it!). So that specific error in CZ has different causes than that which occurs in Vanilla ZH.
