I got to the end of mission 1 where you're told to use Blood Money on Mandalf to advance to the next level. I used it on him (Yellow), it played a little cutscene where he was asking what I bid of him, and then he turned to gold (Mandalf the Gold). The objective in the top right to turn him into gold is still there though, and I can't finish the level.
