Duplicating mesh in editor changes mesh and crashes on play

I have some models in ym project. These models dont use any reference to eachother in any way except an interface. If I duplicate one of the models in the world outliner, the mesh changes to that of another model. If I press play, the editor crashes. I can how ever drag from my project folder into my level. I need to find a solution to this.

Here is a video of the problem and how to replicate it.

Hey Aeregon,

You obviously have something going on in the construction script of each blueprint. Can you show me your BP setup?
