Version 220.127.116.11 (260180) Playing as Egypt, after a nuclear (not thermonuclear) attack and taking Cairo (capital city of Saladin) in the same turn, the wonder Apadana can't be repaired. It shows as (15) turns to repair, but can't be chosen as an item to repair. It can't be emoted either, or built next to my original capital city. All other pe-requisites have been met. I don't have a pre-bug save as I did not notice this until multiple turns later.
