- command to generate prefabs for sale on already generated stations (without the need to regenerate whole economy) /npc economy sellprefabs, this commands can be used to shuffle what ships stations are selling as well, to spice things up
- /npc economy generate & /npc economy station commands will already generate stations with prefabs to sell (base set is coprised out of the ships sold by vanilla economy)
