Stardock has already acknowledged that they have errors in the calculations from artifacts and they have "corrected them internally" and the fixes will be out in the next patch.
Thanks. I only had time to watch about half the stream, so I missed that.
I have no worries about things like this--I know the dev team is working hard and things like this get missed, but that's a large part of why I'm playing the early access--to help them ferret out this kind of stuff.
