Playback Error on MuseScore 3 during (auto)save

There's some bugs that sometimes (mostly) happen on MuseScore 3 Beta when I click the play button.

There's 2 of them; one (1) is that sometimes while playing the song, it skips a part and doesn't play it. It's really annoying sometimes mostly when testing a song with Volta Brackets. When the Volta Brackets are completed and the bug occurs, I have to play it all back again (of course because if I didn't, I wouldn't test the other parts if they are suited to the other first parts). And the Volta Brackets will be active again; the second (2) one is when you are playing the song at any part then clicking the Save button. The result of that is dynamic. It's either going to skip a part, stopping the play button, or distorting the sheet. It's annoying too assuming that sometimes I always click the Save button while the song is playing, it's kind of been my hobby. Now, I'm trying to not click it, which disappoints me...

Anyways, those are all. I wish you would fix them and if so, we would be happy and we'll continue to support. Thanks!

Also, I could upload you a video file for further proof.. But it doesn't work.. An image is all you could upload, but an image can't explain it.. But yeah, thanks still!
