I ve got a problem. Some characters don't work how they should. For example a guy who leads you to Emhyr doesn't move. I tried to re-install the game but it didn't work. Is this a problem with a game or my computer? Did anyone have similar problems? I will be grateful for help.

And I forgot to tell the basic info- the game is Witcher 3.

What game?

(You posted on the General forum about a specific game without mentioning the game. Maybe try the game specific subforum instead?)

Maybe this can help?

I assume it's the only game that GOG has, Witcher 3?

Emhyr var Emreis I assume, so witcher 3 i think

I've got some strange brew, if you want.

Angel of Darkness is notoriously iffy with the controls.

What about this Strange Brew?
