[Spoilers] Fools Gold DLC quest clash.
The DLC quest "Fools Gold" clashes with "the Fall of House Reardon" and it starts the subsequent "Ghosts of the Past" quest if Leo is alive from the Witcher 2 as Geralt talks about booby traps not being set by monsters as you swim around the Hog Hut...
Mulbrydale Swordsmith
Not a huge bug, but the Mulbrydale Swordsmith saved from level 16's in Velen is actually an Armourer and thus incapable of crafting swords.
:wat:
Slightly peculiar.
The world's worst Swordsmith.
