FRenderResource release problem

Hi,
I build my own USkeletalMesh from a custom format. The mesh is first created in my actor’s constructor. At this point if I drop my actor in a scene, I can see the mesh (without materials yet).
The skeleton seems ok, so is the geometry.
When I click “Play”, I’m getting the “FRenderResource was deleted without being released first!” error, without even calling “PostInitializeComponents” or “PostLoad”.
I suspect the problem comes from the destruction of the editors version of my mesh instance. But I don’t know if it’s the bones, the missing meterials, etc.
Is there a way to debug FRenderResource? Get it’s name for example in order to understand which one is the problem?
