Character physics asset (bodies) not collide with itself but collide with other copies of character

Hello guys,

So I have a character and its bones physic are always simulated. sometimes the body colliders pass through each other making the mesh explode. I want to disable all collision between all the bodies but that would stop allowing collision with other instances of the same blueprint and i do want collison between other players. How can i solve this?

Thanks anyways,
Tristan
