Edit./update so i figured my problems were due to missing a key NPC in the prelude, that you cant get in the chapter 3. wish i knew that before the guide came out and i wasted many many hours in chapter 3 itself.
had to load a new game to start in prelude, do the stuff i missed and aaalll the stuff i already did ...again. which is quite a hassle.
Getting locked out from ALOT of content do to missing a few scenes is something that is hopfully number one of the list of things to be fixed, even before adding new content.
Sorry to hear that. You can also skip to chapter 3 next time and it will assume you did everything you possibly could in the prelude.
We're currently working on a new QOL to help with finding out how many people are in an area and the people you did unlock what events they have and the requirements you need to see the event. It will still be up to you to figure out how to get the requirements, but hopefully should help.
