Happened first after the update from BIAB 2022 to BIAB 2023, and it's still there with Build 1003, but less often.
Of course I rebuild the styles and Realtrack databases.
I also newly installed Xtra-PAK 14 and 15, and most issues seem to be with those packages, but older ones have also sometimes this problem.
The new packs where installed into the correct folder of course, and I reinstalled them just to be sure everything's correct.

Log from the installation check:

This will check RealTracks installation. For a RealTracks to work, there needs to be a ST2 file in BB folder, and a folder of WMA files in the RealTracks folder set in Prefs-RealTracks Settings.
Number of RealTracks ST2 found in BB folder = 3661
Number of RealTracks WMA folder found in RealTracks folder = 3661
This will check dates of Bt0/bt1 files compared to WAV and WMA files in RealTracks and RealDrums.
Bt0 Status matches the ST2 - no errors
Drums WMA - no date errors
Drums WAV - no date errors
RealTracks WMA - no date errors
RealTracks WAV - no date errors
