He Mike. Aou can throw them into gemini or any other AI to analyze…easy to spot them like this but if you do long rides it gets harder to miss the errors and spot why the happened and when. There is a variety of errors that can cause the “game engine” in the background to crash or freeze, sometimes it will continue to write a local file (that it can upload later) - sometimes this gets stuck. Biggest issue there is no continues writing or controll/recovery in the file write.
A long time it worked - but the logs still show errors and instability. The game itself will not crash, everything will seem normal till you save the ride and wait for it to sync and nothing happens. Any you notice the fit file stopped writing a long time ago, and no final write was done when clicking "save and exit. "
