The side quests were available (killing X humans or hostiles, defeat Irradiated Bone Sperm Whale, etc), but no story missions. I completed all side missions and have Plover Island's map at 98%, but now I have no indicator as to what to do next. I posted on reddit for help as well, and you can see a screenshot of my log page. One other symptom of blocked progression is that my infamy meter will not reach 3 right now. I can fight humans and hunters until the infamy meter is maxed out, but it will NOT raise to level 3 (no boss hunter appears either).
