This quest is in Act 4, Philosophy Level, from the local vendor (northwestern corner of the screen).
You have to enter the imp's dream - fine.
You get fairy powder and mix it with water - fine.
Picking up the amulet of the quest - fine.
But when you go back and report success new saves made are impossible to reload, they crashes the game.
I initialy thought the imp's dream is the fault given the missing conversation options, but keep pressing 1 is ok.
Also thought it is the Rif Running Maze, but that's fine too (the bug first occured here, wasted a couple of hours because thinking the source is where the problem first occures...).
Again thought it is the Ultimate Answer quest, but managed to filter that out too.
