Hello,
I downloaded the game today so I'm guessing there is nothing to update (also checked with PS updater, there was nothing to update) and I also get this Loading Region Failed error. It started when I went into the sewers from behind the tavern and walked straight forward after coming down the stairs. Then I tried creating a new character to play until this is fixed. I finished the Character Creation and wanted to go into the game but again it keeps giving me the same error.
Too bad really as the game is really beautiful and fun.
Hope to be able to play again soon,
Dorrian
