Help!1

I got to Tunguska---went to the Blisk Base--steps appeared on the alienship for Crypto to fly up and get the Nexus Cryatals--------However on my 1st attempt--I didn't have enough Jetpack power--so I cruised to a few past side missions--then got enough to buy an upgrade pack-----THEN--when I returned to the Blisk Base--the "Steps" leading up to the top--where the Crystals--I assume were---were GONE!!!

So I tried a few "cheat sites"--they all said kill 52 Spore monsters--and then pox will pop up and give you a hint to find crystal #1 aaaaa, #2 and so forth-----mY hANG UP--------i KILLED A GAZILLION OF THESE THINGS---no pOX pOP uPaDVICE gREATLY APPRECIATED.

PEACE;
