The battle_models.modeldb file is not letting my units given to other factions show up in battles, they are invisible or white or silver like Liquid T 1000's from Terminator 2.

I'm doing it correctly that's not the problem, my situation is that my comp recently crashed and lost some files and extensions...

So that includes the modeldb file extension.

I've looked online for places where to download it but it's not even listed in over 4 sites as an extension.

Does anyone have any suggestions, ideas, or know what to do, or a link to where I can download the extension??
