1by1 v1.89 skips some folders but plays MP3 fine if I select manually

[tmcdos]

I noticed some strange behavior. I have a folder MUSIC and there are for example 10 subfolders each containing between 1 and 10 MP3 files. I start playing from the first subfolder - when the 2 MP3 files there finish playing, 1by1 jumps straight to the last subfolder and skips 90% of the other subfolders. However, if I focus any of those skipped MP3 files and try to play it - it plays fine, but again when all the MP3 files in any of the skipped folders finishes then 1by1 jumps straight to the last subfolder instead of continuing with the next alphabetic subfolder.
Any ideas ?

This is still true with versions 1.90/1.91/1.92/1.93
If you have a debug version with logging I can test it and get back to you.

I made more tests and the results are:
1) version 1.72 manifests the bug when using ACM but works fine (i.e. does not skip any file) if using MPGlib
2) versions 1.75 / 1.76 / 1.77 / 1.83 / 1.84 / 1.85 / 1.86 / 1.87 / 1.88 / 1.89 / 1.90 / 1.91 / 1.92 / 1.93 manifest the bug no matter if ACM or MPGlib is used for the playback

Thank you for testing. By now I didn't see this and have no idea.

If the behaviiour differs between ACM and mpglib, may be it depends on the play mode. There is a normal and a gapless mode optionally with transition overlap.

I know one case where a corrupt MP3 is skipped at the corrupted point on normal play - but play fine on gapless. But could not find the reason by now.
