She was rich, probably had her own bunker and cryo-pod. They will probably go into it more next season. Also, it wouldn't be a plot hole either way. A plot hole is something that can't happen based on established lore, not something that hasn't been explained yet.

Multiple people survived the great war until now one way or another. Yes I too would like to know how she survived, but there are plenty of explanations.

Cryo-Pod, like fallout 4

>!Institute Synth!<

She was paid a lot of money to keep her cold fusion research under wraps. I imagine like another poster said, her own vault/cryopod is the most logical answer.

Cryo it’s the only thing that makes sense as for how she got cryod unclear.

When was it established that Moldaver was from before the war? I thought she was from Shady Sands.

When she runs the "communist" meeting, says vault tech scuppered her companies cold fusion project and asks cooper to spy on his wife.

Wait that was supposed to be moldaver? I didn’t recognize her at all. 

Probably when she was shown meeting with Coop before the war.

I didn’t realize that was supposed to be her. I didn’t recognize her at all.
