The codes I added to my game.ini are
NPCReplacements=(FromClassName="Shapeshifter_Small_Character_BP_C",ToClassName="")
NPCReplacements=(FromClassName="Shapeshifter_Large_Character_BP_C",ToClassName="")
ConfigAddNPCSpawnEntriesContainer=(NPCSpawnEntriesContainerClassString="DinoSpawnEntriesMountain_C",NPCSpawnEntries=((AnEntryName="",EntryWeight=1.000000,NPCsToSpawnStrings=("Vulture_Character_BP_C"))),NPCSpawnLimits=((NPCClassString="Vulture_Character_BP_C",MaxPercentageOfDesiredNumToAllow=1.000000)))
ConfigAddNPCSpawnEntriesContainer=(NPCSpawnEntriesContainerClassString="DinoSpawnEntriesBeach_C",NPCSpawnEntries=((AnEntryName="",EntryWeight=1.000000,NPCsToSpawnStrings=("Jerboa_Character_BP_C"))),NPCSpawnLimits=((NPCClassString="Jerboa_Character_BP_C",MaxPercentageOfDesiredNumToAllow=1.000000)))
None of these are working. Can somebody help me out?
