Project with many tempo changes will out of sync after re-open

[eviluess]

I won't upload any project file again.
the stash seems to have size limit.

Here's the story:

I made a MIDI to match a song with free tempo.
And made strict alignment from start to end.

But, after I close the project, and go out for dinner.
When I back from dinner and open the project, the middle part of the song OUT OF SYNC very much.

That range of MIDI notes either later or earlier than the reference audio.

I think Reaper needs to review the MIDI tempo check list for the recent update. especially the mac edition.

I've posted several issues about the MIDI I/O these days.

I remember that the Windows edition wouldn't have the similar issues.
