I'm not sure if "missing" is the right word, the automata is there, but it seems as though as they drive they leave a "shadow" that stays in one spot and everything behind it disaperes behind it. Are you with me folks? hard to explain, but have a look at this picture and see if you know what I'm talking about. A video might be better but this will have to do.
Any help on how to fix this issue will be GREATLY appreciated as it is very annoying, and will certainly interfere with a UDI video I plan on making.

If you're using hardware rendering, try disabling Anti Aliasing or switching to software rendering. I've seen a similar issue with my ATI card. Disabling AA resolved this for me.
