Is it only in the frontier that you cannot move Connor ? can you fast travel somewhere and he will move ? or is it when you continue the game you start in the frontier and cannot move ?
Have you tried restarting the memory or a different DNA point to replay a section through the frontier ?
Yes it is only in the frontier, I can fast travel but everywhere I teleport myself it's the same. And yes when I continue the game I start in the frontier and cannot move

I tested to restart a memory (I could move) but not in the frontier.
