Is it normal that every time they put an update the previous saved games go to shit?
Depends on the save. Some saves for me goes to shit because i think Andy change the Script on those parts, so the game cant reed those.
That kinda sucks lol, I have some routes that I'm pretty far on and other I just started so I wasn't expecting to click through the entire story again (not that I won't reread it, but just saying)
