I recently tried to replay two flights from last year, one from early september and one from early october.
however the files were corrupted (the aircraft doesnt have landing gear, and it either sinks, or floats up into the sky)
i find it odd because they used to work fine, and I also have files older than them that to this day, still play back perfectly fine.
If these replays do as you’ve described, it sounds more like you had a connection issue during the original flight. Have you ever viewed these specific replays before?
