Hi Euphoniac, thank you again for the nice feedback, I deeply appreciate it :)
I apologize for the broken events (unreadable books and crashing map) I checked and I missed those errors, thanks for pointing them out.
I uploaded a 'Bug fix - Broken events' which contains a 'data' folder you need to replace inside the 'www' folder. (backup the previous data folder in case it doesn't work)
After that, you should be able to interact with the books and proceed with the story. The Forbidden Fortress warp should be working now, too.
Let me know if it's fixed or I can check other options to solve the issue.
