This may make the song start honoring the RB standards (instead of RB trying to honor the BiaB format)
Once saved as SEQ file;
Then highlight the desired tracks from measure 241 forward and regenerate those .. or maybe highlight the desired tracks and regenerate the whole song.

If you opened a BiaB file and never saved it to SEQ format, maybe RB is still dealing with the 255 limit while trying to work with a file in the BiaB format.
Just a thought

If I open a BiaB file in RB I always immediately 'make all BB tracks regular tracks' and save as a SEQ file so RB behaves as expected .


Well, I figured out how to convert BB tracks to RB tracks. This command is actually on the "Edit->Track" submenu rather than on the "Audio Effects" submenu. Anyway, before I did that, I cut out one entire section of the song (Interlude, verse, and chorus) to reduce the number of bars to 223 and then generated the five BB tracks. After doing that, I saved the file as a SEQ file and then reopened it in RB. Then I converted all the BB tracks to RB tracks and replaced all those bars (102 of them) for that entire section that I had deleted before so that I would have my complete song back again in RB format with the entire arrangement (RB copied the audio for each track as well). Then I saved the song again under a different filename. Next, I tried to re-generate all the tracks again as RB tracks, but RB said that "there are no previously generated tracks found to re-generate." So, it looks like the arrangement generation of tracks is strictly a BiaB function that is limited to 255 (or 240) bars, which means that RB does not resolve the 255 bar limit in BiaB without also abandoning its automatic arrangement generation capabilities. That is, unless I'm missing something or didn't do something right.
