Just completed my first conquest victory and noticed even after I destroyed all AI Dregin shipyards they were still able to spawn ships. Also while upgrading planets I see the Xeno Medical Center takes over 4 trillion turns to complete. I dont know if that is a typo or not but it has discouaged me from building it. I can provide a screenshot so show the rediculous number of turns listed to complete Xeno Medical Center. Please check this and let me know if you need a screenshot of build menu for Xeno Medical Center.
