I've found out that progressing / starting main mission in other player's server 'does' sync with single-player playthrough (progress-wise). BUT turns out, it doesn't sync other things like outpost. Although I managed to open some shops by playing main missions all over again, it was impossible to activate tech console dispenser. Is there any solution for this problem? I know I can purchase tech console from co-op server, but I want to activate it for my own.
