[ergoxiv]

Changes:

• Removed the "None" as a selectable option from the age customize editor menu.
  • Note: It is used internally to determine if the model is a non-humanoid NPC but it should not be selectable by the user.
• Fixed infinite actor refresh loop causing flickering and game crashes.
• Added thread locks to resolve an issue where the history class might occasionally try to record multiple elements at once from differen't threads, causing Anamnesis throw a critical exception and close itself.
