Okay I have a problem. When I reach the end of a chapter it gives me the option of pressing X to play it again or pressing A to continue. If I press X it warns me I'll lose progress, then restarts the chapter.

Fair enough, working as intended.

If I press A.... It simply restarts the chapter.

I got past Chapter one on the fourth or fifth try by reloading then going back and knocking out a few more guards (changing from opportunist to ghost) and that time it let me through. So far I haven't been able to get past Chapter 2 at all. I've tried returning to the ci y and then reloading to my c2 save but it still won't let me get past it.

Any advice?
