oh another one I forgot. I had a race of beings evolve on a planet with no spice, in a system with no other planets, and I started a trade route with them and bought the system.
When I first saw them in tribal and civ stages, their world was normal, mostly (no spice nodes, but lots of villages and cities in civ) but when they became space faring, all but 1 city 'blew up' - the spots where the cities were are still there, look like ruins, but only 1 city exists.
Indecently it produces red spice in normal amounts, even though the planet has no spice nodes
