What you can try is copying another section of track earlier or later with the same chords and paste and replace that section
or copy that section's chords to somewhere after the ending,
increase the number of bars to cover it,
select that new section of chords and all the tracks
then generate all selected track in section,
then cut and paste that into the bad section,
then set the number of bars back.
Thanks for the suggestion. Unfortunately, I've done this already and found out that it's a relatively slow process compared to when I did a very similar process in Tracktion 6, which is my preferred DAW for this purpose because of its simple GUI and minimal use of resources (as I mentioned in a previous post). IOW, your suggestion is the same workaround that I've used in the past but with a different program. To me, this does not "resolve" the "255 bar limit" in BiaB. Tracktion allows more than 255 bars as well. It just doesn't generate tracks like BiaB does. So, it's much easier and quicker for me to save a shortened version of a BiaB generated arrangement of my song that I can then import into Tracktion, replicate, crop, and then piece together into one contiguous arrangement. Using either program is fine if I'm creating a single arrangement for only one song. But if I have to create multiple versions of an arrangement for that song because of mods, tweaks, and other enhancements, it can easily consume hours and hours of time. I know this from experience because I went through it a couple of months go. This is the main reason I shared my "idea" that started this discussion about a week ago.
