Doesn't really sound like any big deal, but what the hell do we know about what's a big deal?

[it's not like they know how they ended up in ice-age exsilium instead of flattened-by-nukes exsilium, either.]

There was a movie like this, back home, a guy living the same day over and over while nobody else remembered it. Except I'm pretty sure his time loop got fixed when he got the girl. But since he had pretty much all the time in the world, he learned to do all kinds of stuff. So if we're stuck, maybe there's time to figure out why.

...when did those new people show up, though?
