Action RPG Inventory System

This is an art export issue. Make sure your head asset is skinned to the skeleton headbone and exported out properly before importing into unreal.

Sounds like a bug with unreal and structs. You are using 4.10? I know in 4.11 a lot of struct issues were fixes (not all but it was a good start).

I will test with 4.12.5 when I get a chance and let you know if the bug still persists.
