I would rather not have to replay the entire week 2
Well, you can always wait for the final version...after merging all the weeks in one game you need to restart anyway ^^
Otherwise i recommend reading post#1, especially the red text...and you better have a endsave from week1, or you dont just need to replay week2...be aware your content (cen, uncen, uncen+) will also be in this savegame, so you can only continue but not change this setting, only with a new game you are able to change this.
btw, there is no import button on the main menu...to continue from week1 you need to start "a new game" in week2 and select your endsave.
How do you enable uncensored/uncensored+ modes?
After patching week1 you need to open the options and choose your version (i recommend uncen+, that way you have both, the cen and the uncen choices...dont worry, the cen options will be marked), then start a new game and play week1 until the endsave. You cannot change your mind midgame, only a new game will allow you to change it.
Week2 will take over your settings from the week1 endsave, so be sure to apply the week2 patch if you played week1 uncen(+), otherwise you dont need it.
P.S:
Use save/quicksave instead of rollback if you wanna try other things. Be happy this dev is not as cruel as others (in some games you need to backup your persistent and autosaves if you wanna try other options because they lock other choices even after loading savegames)
