I need to do this to move on in the game, and I am willing to do anything...
But I was wondering, is there any possible way to 'cheat' the game and complete a quest in The Witcher 3: Wild Hunt? I will do anything in order to complete this quest including using other means than completing it legitimately, because I am unable to do so because of a bug. The quest in hand is
The Play's The Thing and if you want to read my problem, it is a separate question on this arqade account.
However, a solution for all quests might be more useful for other people with a similar problem.
As I said, any solution will do, whether that means installing a client or modding the game files. I have already tried console commands, but every source I have looked at does not seem to give commands that directly affect quests (e.g. finish.current_quest).
