No-one can accuse CD Projekt Red of lacking commitment when patching and updating The Witcher 3 (one can argue they might have done so before launching the RPG, but that's another conversation). The developer has since released a new update for the game, Patch 1.11, that introduces a number of improvements, not only for the original game, but also for the Hearts of Stone expansion and even for the smaller DLC drops they've released for free.
You can read the full list of improvements right here, but we have to highlight the fact that the brilliant "Skellige's Most Wanted" mission is finaly working as intended.
