How i did this? Whenever they mass spawned i culled them in cycles in small numbers from each species taking lowest % 2-3 animals from each species then jump a year/cycle and repeat process climbing in genetic % until each animal species left on mass frozen group had like 15-20 highest fitness % at last age then just let them die off each species bear has the longest lifecycle so was last on groups.
Then i just kept repeating until mass spawn groups got smaller and smaller and at one point i just went 30 cycles continously whitout any culling logiing in and out of the game each 4-5 year cycle.
At this moment my game seems ok whit few maintenance of herds of same age wery few left.
Its a kind of pleasant cheating and experimenting you end up whit a pile of cash and xp to unlock half of the skills at least im at level 28 and 160.000 cash but doesn't matter for me no spoiler since i do moostly bow hunting only and i don't really care about the rest of the items.
So long story short im curious how long will last this "fix" for me im going strong since two days like this no issues and im realy checking the map all over constantly i have tnets on high mountain and hill topps and tent trawel and scout and also roam around whit the car constantly having a last tent and hunting tripod seting up at the car so i can spawn and continue where i left,the proces since its wery engaging and interesting the yield results upon exploring since herd fitness % went up considerably on all over the map and spoiler alert alse yield some rares that thankfully are not frozen because they are din different age group herds so wayt to age them to last year checking on them while scouting.
