I've run into some strange behaviour when splitting regions (split at playhead) in order to make gain changes. Sometimes the region before the split doesn't show a fade-out and it can't be added manually. Subsequent dragging of the end and attempting to make a cross fade still doesn't show any fade-out on the end of the earlier region. It appears not to be just missing from the GUI as there's a pop on playback.
Undo seems to get confused by the above and doesn't undo all the actions. Subsequent repeats of Undo sometimes causes all regions and beat/bar indications to disappear, leaving a blank black area (and no sound on playback). I've tried to reproduce this behaviour in a small test project but it behaves properly. The issue occurs most of the time in medium sized sessions (16 or so tracks). For now I'm working around the problem by editing gain changes in mhwaveedit and importing the modified files back into non-timeline. When I get more time I'll submit a Github issue, but I don't have enough info to make a meaningful bug report yet. John
