I don't think it's the problem of the rig, rather it's the game engine.
Check ReleaseCrashInfo.txt on your C&C General Zero Hour documents folder.
If it doesn't provide the error within the first few lines, then it's the game engine crapping out on you.
One possible factor is, what maps are you playing on?
Another cause for it is that sometimes the engine does a derp and will fail to construct a unit(eg. War Factory opening but no unit is coming out), which will cause in a crash.
