After beating the main story line, I tried to go finish the rest of the side quest but when I travel to far from the Beauclair Palace theres a barrier as if I am at the end of the map. I know I have defeated Dettlaff but it seems Geralt forgot, then the map pulls uo. The only way I can get pass it is if I fast travel out side if the barrier, but when i get gack clode to the barrier the same thing happens and some of my quest leads to that barrier or islocated in the barrier.
