I'm not sure anyone ever reported this, and it's not really a big issue, but I've noticed since a while now that most helicopter-flights (not all, but most) don't show a "helicopter'-symbol on the helipad as indication that the flight is completed. I have to click the flights-window and select the "speed up for free"-button / "Complete"-button as if the flight is in its final 30 seconds before completion. Even after waiting for 30 secs (or a couple of minutes for that matter) the icon that you can usually click to finish a flight doesn't appear. I still have to do it by manually clicking "Complete". This has been going on for a while now, and like I said it's not really a big issue, but I just thought the dev-team should be made aware of the issue.
