what is your video card? and do you have the advanced lighting on?
I get the same on my low geforce (7600gs) in the beta4's, but on my 8800gt & ati's allwork properly.

Yes, 7600GS Nvidia... seems the problem is only with my sovereign. I will try with advanced lighting turned off.
UPDATE:
Problem occurs even with advanced lighting turned off, but performance is 10times better with advanced lighting turned off. Problem can occur for any type of unit in battle... unknown what causes the issue. When the issue occurs I am unable to see the battlefield or any units, then afterwards the system/game crawls so I have to exit and reload.
