I recently researched temporal technology to obtain the temporal space yard. However, when I try to upgrade, nothing happens. Do I need to scrap my existing Space Yard 1's and then construct the new temporal yards?
It may be that I need Space Yard 3 before I can upgrade to Temporal. However, it seems it would be better to scrap the yard and rebuild to avoid the research costs, time, etc. Am I right?
