I’ve been playing one scenario for about 5 hours in total (not continuously). At the beginning I saved and when I returned later there were about 4 aircraft parked at their terminals with no information panel and they’ve remained there ever since. It’s like they are there but they are not supposed to be because some aircraft are landing and trying to park at the terminals occupied by these ‘phantom’ planes. I can’t even delete them because there’s nothing to click on to get rid of them. I’m sure it’s a bug.
