Changing DM's simulate physics at runtime doesn't work

Hello, I’ve been tinkering with Vive and UE4 recently. I tried to set up something like the ball tossing game like Sam Deiter and Wes Bunn did in this video: link:their carnival game video

The difference is they are using static mesh and I’d like to use destructible. The setup is basically the same as they did and I’ve spammed my blueprint with prints so I know that everything is triggered when they are supposed to. But the result is just sad: when I release the button, the DM blueprint actor detaches and keeps its world transform.

I see this post:answer hub post and it seems awfully similar to what’s troubling me. But it doesn’t look like the OP has got an answer yet.

Cheers.
