This is still a problem, with mouse and keyboard. Cannot change signs once you begin the tutorial. Before that, you can select normally with mouse scroll, and if you choose quen before you start dueling Vesemir, you can get past Quen. Then he asks for Igni, and you're screwed.
I can't remember if there are any achievements related to the Prologue, if so, this is a "game breaking" bug that has existed from launch? Obviously it only happens for certain people, but it is in how this portion of the tutorial is coded. I only lose mouse scroll after I draw my sword. Loading an old previous save, scroll works fine.
I find this frustrating as hell. I just finished a nice W1/W2 run and want to finish this Geralt's story. I also want to see all the content I can. My only option is to quit this new game and start a new one skipping the tutorial.
I know the game is old- but for crying out loud, this is the game's tutorial that is literally built for teaching new players how to play, and it is broken. If you are still going to release a next-gen update for this game, will you please look at fixing a very old bug that comes at an important starting point for every single one of your new customers?
That'd be great.
