The point should be that outside of a warhammer 40k scenario where operators and engineers don't properly understand their own technology due to regression, if you dump 50,000 organized post modern people on a planet they should be building cities with at least some semblance of modernity.
At the very least they should be laying out a (spread out for usable green space mind you) grid city of rammed earth buildings with running water and heating.
Not just wandering around in fields with a thousand yard stare. You can't live out of a back pack.
As far as I'm concerned everyone died within a month.
