Beat is skipping due to too many subdivisions
I recently encountered this issue where the playback skips a beat in Musescore 2.1. I believe this is due to too many subdivisions being encountered, and the engine not being able to properly handle it. In the attached PNG file, on beat 4 of the first measure, the beat skips to the next measure. In beat 4, I have a note offset by a 16th note duration, an 8th note followed by two 32nd notes and a 16th note, and a division of 7 all occurring within the same beat. I also have a 70% 16th note swing notation marked to begin on beat 4.
