really you cant get a stable eco? i have this one running just fine... also update.. i've modified the sets for a river type sim mostly because evo had slowed a bit.. now explosions in diversity of plants but in one they've become semi cancerous trying to get the animal now to evolve more too to help keep them under control, tweaking the sets slightly.
so to enable a river type sim i put in a little gravity and fluid density to it. then i put in 10 random shapes with drift on although i think its a bit too fast even on the slowest settings..(i personally like extremely slow to let evolution take place a bit first..) unfortunately animal is a bit too slow on mutating now and almost stopped evolving. however i do have 2 stable animals in the same eco although they aren't very different atm.
nice btw bots, is that the one you've been evolving here lately? also i you want some tips on getting a stable eco i might be able to help on that.
