I have this issue again on a different file, AxisCamera. I was adding a saving function, and it started doing it. I was editing it, save, compile, add more, etc... and I added one line, and it started doing it, and won't stop. I commented my chages, even completely replaced the files with the default WPILib's, but it does the error now. Rebuilds make no different.
errors:
