While going through the Roll20 Starfinder Core Rulebook in-game I noticed a couple sections where information is missing in the Compendium. I checked this information out of game as well, just directly in the compendium to confirm it was missing. Everything I've found is under "Chapter 9- Starships". This first bug is under subchapter, "Primary Systems (starships); subheading, "Base Frame". The compendium proceeds to list the base frames of the starships in list order without any accompanying stat information (Reference 1). These entries are not hyperlinked to elsewhere in the compendium; they appear to be missing entirely as a direct search for any of these list entries will come up empty. I provided a screenshot of this page in the PDF of the Core Rulebook to illustrate the missing stat information (Reference 2). This next bug is almost directly under the previous one. Its in the same subchapter, "Primary Systems (starships)" under subheading, "Thrusters". The compendium proceeds to list half of the accompanying table (reference 1). In the Core Rulebook PDF you will see that the table under Thrusters continues onto the next page (references 2 and 3), the compendium cuts off at the first half and does not list the rest of this table. The rest of the table cannot be found in the adjacent Compendium entries, "Other Systems (starships)" or "Weapons (starships)", or elsewhere in the compendium. This last bug occurs in subchapter, "Other Systems (starships)" under subheading, "Drift Engines". The compendium references an accompanying table listing drift engine stats but none is provided (reference 1). In the Core Rulebook PDF you can see there is an accompanying table with drift engine stats in this section (reference 2).
