I run a server that has Primal Fear as well as just about every PF Exansion Pack (except Noxious) and recently implemented SimpleSpawners when we were having dino spawn issues. I have done some testing, and can get nearly all Primal Fear dinos to register in the mod by adding the BP path, but the dinos from Primal Fear Boss Expansion do not work. For example, trying to setup a spawn for a Chaos or Apex Dragon, but when I go to add a blueprint it does not give an acknowledgement. and doesn't not show up in "Custom" on the left pane.

Here is an example BP path for one of the dino I'm referring to:

Blueprint'/Game/Mods/Primal_Fear_Bosses/Chaos/Dragon/PFBChaosDragon_Character_BP_Child.PFBChaosDragon_Character_BP_Child'

Any thoughts on why I can't seem to setup a spawner for these dinos?
