Destructible Mesh destroyed after one shot

Development Programming & Scripting

I’m playing around with some destructible meshes and this is what I’ve set for the hit event to cause damage to it.

However, even though it’s set to do 0 damage, the mesh is exploding after one hit from a projectile, or if the player character touches it, it also explodes.

Any ideas on what’s causing it to happen?

I can post the other blueprint stuff if you can let me know what you need to see.

Thanks
