The issue is old. If you use the "unlimited time" units, those units will remain on the battlefield, till you disable the option. You have to select the units, before deactivating the option. Picture it as choosing what to mod, enable - choose what to mod, disable. That's how it works
I have been working with the new trainer and so far the onlything i can find is that instant build is two sided and that the health options don't work anymore. thanks for your help pwizard.
