In a Facebook post, Airport City said there are a number of changes in their latest release. I have the latest, but I don’t see either of these: 1 Reworked the contracts in the Fuel Station. Thanks to all the innovations, fuel production is now more profitable! 2 Limited the amount of times you can ask for gifts. Only 20 requests every 12 hours. I see no difference in Fuel Station, and I get to gift every 24 hours. It is possible that I don’t understand that second one, because the only way I have ever requested a gift is to send a gift. Regards, all.
