So I'm trying to make Alpha Direbears and Silver Zomdodos spawn more often in Ragnarok in my singleplayer. So far I've got this in my game.ini file:

Replacing common creatures: (Only left me with brontos and no direbears/silver dodos at all)
NPCReplacements=(FromClassName="Dodo_Character_BPElite_GNS_C",ToClassName="SilverDodo")
NPCReplacements=(FromClassName="Ptero_Character_BP_Child_GNS_C",ToClassName="SilverDodo")
NPCReplacements=(FromClassName="Dimorph_Character_BP_Child_GNS_C",ToClassName="SilverDodo")
NPCReplacements=(FromClassName="Para_Character_BP_Child_GNS_C",ToClassName="SilverDodo")
NPCReplacements=(FromClassName="Trike_Character_BP_Child_GNS_C",ToClassName="SilverDodo")
NPCReplacements=(FromClassName="Ichthyornis_Character_BP_Child_GNS_C",ToClassName="SilverDodo")
NPCReplacements=(FromClassName="Direbear_Character_BP_Child_GNS_C",ToClassName="Direbear-Alpha-Baby")
NPCReplacements=(FromClassName="Dodo_Character_BP_Child_GNS_C",ToClassName="SilverDodo")


Increasing Spawn Weight on Silver Zomdodo and Alpha Direbear: (No changes sadly..)
DinoSpawnWeightMultipliers=(DinoNameTag=SilverDodo_Character_BP_GNS_C,SpawnWeightMultiplier=100.0,OverrideSpawnLimitPercentage=true,SpawnLimitPercentage=100.0)
DinoSpawnWeightMultipliers=(DinoNameTag=Direbear_Character_BP-Alpha-Baby_GNS_C,SpawnWeightMultiplier=10000.0,OverrideSpawnLimitPercentage=true,SpawnLimitPercentage=10000.0)
DinoSpawnWeightMultipliers=(DinoNameTag=MegaDirebear,SpawnWeightMultiplier=10000.0,OverrideSpawnLimitPercentage=true,SpawnLimitPercentage=10000.0)


I just don't see any alpha direbears or silver zomdodos even hours after a destroywilddinos command. Can anyone help?
