In case anyone needs help adding these to their game.ini

This should add them to The Portal and other "easy" areas
ConfigAddNPCSpawnEntriesContainer=(NPCSpawnEntriesContainerClassString="AB_DinoSpawnEntries_TwitchFertileLandEasy",NPCSpawnEntries=((AnEntryName="EggoRaptorspawner",EntryWeight=0.5,NPCsToSpawnStrings=("EggoRaptor_Character_BP_Aberrant_C"))),NPCSpawnLimits=((NPCClassString="EggoRaptor_Character_BP_Aberrant_C",MaxPercentageOfDesiredNumToAllow=0.5)))

Here is a list of all spawn containers for Aberration :

AB_DinoSpawnEntriesRockDrake
AB_DinoSpawnEntries_Basilisks
AB_DinoSpawnEntries_BioLumCave
AB_DinoSpawnEntries_DrakeTrench
AB_DinoSpawnEntries_ElementCave
AB_DinoSpawnEntries_ElementWater
AB_DinoSpawnEntries_ElementalChamber
AB_DinoSpawnEntries_FertileCave
AB_DinoSpawnEntries_OctoBat
AB_DinoSpawnEntries_RockDrake
AB_DinoSpawnEntries_TwitchBioLand
AB_DinoSpawnEntries_TwitchBioWater
AB_DinoSpawnEntries_TwitchFertileLand
AB_DinoSpawnEntries_TwitchFertileLandEasy
AB_DinoSpawnEntries_TwitchFertileWater
AB_DinoSpawnEntries_TwitchFertileWaterCave3
AB_DinoSpawnEntries_TwitchFertileWaterEasy
AB_DinoSpawnEntries_XenoQueens
AB_DinoSpawnEntries_Xenos
SE_DinoSpawnEntries_ChupaCabraSurface
DinoSpawnEntriesBee
DinoSpawnEntriesChupa

These were taken from the wiki and included lists of creatures that spawn in the containers as well, but some may or may not work. I have been able to get the biolume cave, fertile areas, fertil water and biolum land spawns to work personally and not yet tried the rest.
