Forum:Reset quest problem

Hey guys, i was playin the mothership zeta expansion but i never use to make a lot of saves, so my last was right before i departure from point lookout. I finished the quest "Not of This World" and started the "Among the Stars" one. I talked to the guys i unfrost, and i thought i had took Elliot Tercorien to follow me. So i went into the Cryo Lab. He didn't followed me so I wasn't sure if he could follow me in this place. I destroyed the generator and went back on the Engine Core. Then i checked the wiki to see if i had forgot to do sth on the Lab, and found out that i could un-freeze two of Elliot's mates. I had changed interior more than once, so I can reser the autosave before gettin for first time on the Cryo Lab. Have tried to reset the Quest but unsuccessfully. I think that i should reset the cryo lab interior first in it's original state before attemptin to reset the quest. Please help me reset the quest where i want to.
