I agree with that. If vegs just keep repopulating it won't be a progress in IM. It's more interesting to see how it evolves and which bots will be dominant. If some species gets extinct they shouldn't just magically appear again. The problem is though that there is a limited amount of bot species and I'm bad at writing new ones. I only have 2 zerobot species, so it's hard not to restart with a new sim and try again, so I don't know.... Restarting is kind of the same thing as repop. Hmm...
