I do run two instances of sims connected with 3 teleporters, but the veggies in this (the right) aren't coming from the left one. I don't have this species in the left one. They all seem to have unknown parents. The teleporters only goes one way, from left to right, unless backflow means they can go back. Also I noticed the teleporters sometimes drag along autotrophs from my left sim to the right despite I have autotrophs unchecked in the teleporters, but those are just NRG providers, no alive bots so to speak.
By the way, do you think you can make it so teleporters are saved in the sim?
