I’d love to know the source of the liveries.
The fact that they showed up means you have them, the only other explanation would be they were surreptitiously testing something regarding live livery download, which is super highly unlikely for a number of reasons.
Question: Have you loaded any livery addons?
If you have, and it only works occasionally, the occasional aspect could have something to do with the time of day you fly and the liveries you have loaded, as well as the success rate of the Live Traffic to download real data that happens to match the livery selection you have loaded. After that it depends on how well the developer set up the aircraft.cfg files for those liveries to have the correct data for matching.
I have no clue why it’s so hard for developers to get it right. Why is it so hard to get the ICAO data correct? They so often just write what they feel like rather than do 10 seconds of searching on the ICAO dataset website. It’s also so easy to get the ATC call signs correct for aircraft type, and nearly every plane I download has that information set up incorrectly.
Fortunately, I’m on PC, since I have to correct nearly every plane I download. This is one of the major reasons I won’t buy from the Marketplace, since the aircraft.cfg files (which contain no proprietary data) are still being encrypted.
But my “correcting” the files is also in itself a problem, because by changing the files, well, even though they were wrong and are now correct, now they’re different from the rest of the Live Traffic/Multiplayer space that has those same planes and liveries. But, I’m doing it based on the belief the AI system is more likely to find matches on my system if the data in the files is correct. And I hate seeing Pipers at gates when developers put “Any” in the parking field.
