Hi Bowman! Sorry I didn't see this earlier (have to sleep sometime). When the module was converted for Roll20, the team determined that it was too big for efficient gameplay. So the later chapters (which follow one of four different plotlines, depending on season) were split into four different add-ons. This is detailed on the marketplace page, and in the Roll20-specific handouts in the module, but nevertheless, a lot of people miss this. Whatever you do, do not try loading all four seasons in a single game. Although Roll20 runs more efficiently these days, the add-ons will overwrite each other in spots, or add a tone of duplicated content in others, IIRC.
