After reading my advice, clearly.
One thing I'm finding really annoying in The Witcher is that some characters move around, but the quest log only points out one possible location. I ran around all over the city looking for a dwarf until I finally found him in a place that I'd checked several times before, but apparently not at the exact time he's there.
It wasn't anywhere close to where the quest log said he'd be.
Also, poker sucks.
