Thank you, ArquesMartin, I'm sorry that you've encountered a bug. I'll fix it as soon as I can.
The demo "ends" once you unlock 3 "grey" areas that you can't visit. Since you've seen the blockade and the tree in the swamps, it looks like you're done.
I'm not sure how exactly is the Archive going to work closer to the release. You're not the first person that is not satisfied with its current state, but trying to make it more complex is going to be very difficult. I was hoping to make the Journal play a similar role, since it summarizes various information about characters and quests.
Thank you so much for your feedback and I'm glad you enjoyed your time!
