I'm enjoying dead money and I started it at level 29 after loading an early save. I did Fires in the Sky and Mixed Signals without any problems. After returning from Mixed Signals (I did Fires first), Dean was nowhere to be found. He was no longer at the fountain. He was not at his initial post at the house in the Residential Area (shaped charge to blow out your ass?)...and he wasn't anywhere in Puesta del Sol. I don't know what to do. Anybody else have this problem?

I am having the same issue but with god/dog. I did he first 2 quests, came back to the fountian to do the 3rd, and he is no where to be seen. The quest marker for "Fires in the sky" is in the far SE corner of the map. outside of any viewable map area.
