I feel like an idiot, but after coming back to Rimworld after a break I cannot, for the life of me, find the research for Artificial Ecosystem. I only have Vanilla Expanded mods installed, and I have installed all of them except for Vehicles Expanded.

If someone could tell me where it is, I would be very appreciative. I have a volcanic winter starting and it has suddenly become relevant to some of my pawns survival - and they need to live so I can rip their genomes out.
