4.12.5

After DM debris timeout (around 10 seconds by default) the editor crashes and vanishes.

It happens consistently.

I don’t think I’m doing anything odd here. Just trying to make the debris disappear.

Ok I found what may be causing it. Changing the **Collision response channel** on _ **Fracture event** _ seems to be causing the crash with the settings above. It’s definitely that + Debris timeout which causes the editor to vanish (crash).

Ignore the multi channel mess I made, I was other debugging stuff.

But this + “debris timeout” on the DM causes a crash.

Hi ,

I’ve submitted a ticket for this that you can follow here: [Unreal Engine Issues and Bug Tracker (UE-35604)](https://issues.unrealengine.com/issue/UE-35604)

Essentially once the destructible has fractured and the new channel is set will cause the crash. I was able to reproduce it using just this simple setup:

Thanks!
