Sure thing, I assumed the seed only affected terrain, so I didn't try it. The seed is 1420311264. Just checked, but I only had time to generate two worlds.
See attached pics. The first copy was nearly identical; the ruin spawned exactly in the same spot as my first world. The second one had "the Alamo" ruin nearby, but the 'parapet wall ruin' didn't intersect the trader this time. The first three seed generations did not have any of "the Alamo" ruins near spawn.
I'm curious now what other loads would produce, but I'm packing to leave - don't tell mom that I'm going home to play more VS! I can't wait to install on my game system - it runs well on this laptop but I get frequent rubberbanding (integrated Intel 520).
Addendum: To be clear, the first reproduction was done through the 'Edit world' and 'Copy this seed to generate a new world' option. The next one, I generated a new world and typed the seed in.
