It seems like the expiring production buildings (Genie, Goddess of Wishes, etc...) are set to expired after their last production is triggered, but before they should be set to expire.
IE. My GoW said it expires in 12 hour, then the production triggered a few hours later and the building was set to "Expired" state prematurely without giving the final production.
