BTW all 3 work units that found a prime were from one of 2 9755's. I love those baby's !

I've tried to bunker some stuff for the TdP Mountian Stage!!! I think I've maxed my home uploaded for an hour or 2!

Anybody here gotten a mountain stage prime? I didn't bunker for it, and didn't switch most of my stuff to GFN-17 until halfway through it but nothing here so far.
