Lately, I’ve seen a crash on exit happening when using Cabbage plugs in Reaper. This is on Windows 10. Closing a Reaper project containing more than one Cabbage plugin makes Reaper crash. It looks like there is something happening when it closes the next to last one. It took me some time to realize this was not related to more advanced features, but not I got it happening on the simplest of my plugins too.
Just for reference, attaching the one I tested with just now. A simple lpf18 with distortion and a flanger. Put this on track 1, duplicate the track until you have 3 tracks. Save. Close the project. For me it crashes while Reaper displays 'Removing track 2
