Not sure why, but the dark side I can't see anything. I see my unit icons, but can not see land terrain or units when planet is in the dark side. Could not find a bug for this. Rebooted and still same issue. Player about 2 days ago on a map I made and was fine, made new map today and now this issue.
I think it's related to a nvidia graphic driver update, i have the same, and some others and its gonna be fixed soon. I think i read that at least.
Yeah it's a bug with the new NVIDIA graphics drivers, it's also present if you have an Intel HD graphics card. A temporary work around is to disable "ambient occlusion" in the settings before an update comes and fixes it.
