Hi! In my previous ultra-hard settings I had nest expansion set to max. To build my base I cleaned many nests, bringing to 70% the "spawner kills" influence to evolution, which jumped to 0.23 very quickly. It became impossible to continue due to too many regenerative biters (which I can't beat without fire turrets).
I restarted my game with slightly easier settings, removing nest killing as an evolution factor. I now began to kill nests again to build my base, evolution is just 0.08 but during the purge both spawner and regenerative factions spawned, just like before, as if evolution didn't influence at all nest types. However reading around this mod's page I see that nest types are influenced by evolution. Is that a bug or it's supposed to happen? Last time regenerative biters spawned around 0.17/0.20, not at 0.08 evo.
