Opening a new thread so it's clear. On 20.0.41, removed all ;# files, I have cue files set to not import. I have removed files set to not get added back.
For the record:
0) Upgraded to 20.0.41
1) I removed all the files
2) Ran auto-import
3) Checked the smartlist to find these things, they were not there
4) I closed MC, reopened it, they were still not there
5) I reran auto-import, they were still not there
[all of 1-5 was 11/21 3:00 PM PST]
6) This morning, I hit play, everything plays twice
[it imported them on 11/21 6:40 PM PST]
