<< I've been wondering if the silence tracks are somehow gumming up the works. >>
No. BIAB recognizes silence to be the same as any RealTrack. That's it's purpose.

<< Multistyle is practically incompatible with regeneration, Daw option required. >>
Also no. My version has 11,165 styles and within that total, 1,014 are PG Music MultiStyles composed from both MIDI and RealTracks. Any Style can be converted into a User MultiStyle in either a single song use, or as a custom MultiStyle for use in any project. PG Music uses MultiStyles and RT1152:Silence a lot in their Demos. MultiStyles have existed in BIAB before RealTracks were introduced to the program. Possible a style or track has gotten corrupted but doubtful of an incompatibility with the program of either feature.
