Not necessarily a bug but a feature suggestion - Offer different win conditions, I have found that in many cases a command unit can be rushed leading to a very early end to the game. Users may find it desirable to continue play until they no longer have any fabricators/factories to build with or even require destruction of all enemy units before win condition is met.
Developers are going to add many win conditions to release i think, it has been discussed many times on the forum. i will link to the tread if you would like to read it
