It was on ERAS which by the way, is awesome. So, i updated the game and launched it as per, i had a save where i was on the world map, i loaded it and the F2 Menu showed as per usual, and i would click on the log book to look at my quests, it wouldn't show the list it would just take me back to the world map with a slight flicker as i clicked, as if it was going to pop up but it didn't load. I can record the gameplay, if you want to see it in action.
I checked to see if the Logging option was checked and it is, also, i noticed that after i click the logging book and it doesn't show up and takes me bacl to the map, If i press F2 to bring up the character page again, it loads and closes very quickly. The Sabeer mouse pointer pops up for less than a second as if i was on the character page and then it disappears and takes me back to the map. and i have sent you the files to your email :)
Got your email and the system.log tells us the problem is a missing questbook.ini file. Not sure why you don't have it, as I verified the source for the Itch upload does contain it. Maybe the Itch upload tool glitched? Or the download glitched? Anyway, I sent you the missing file in an email reply. Let me know how it goes.
