I took out direct support for DM in 4.18 due to it now being a separate plugin and off by default, I didn’t want to tie the plugin into something that isn’t on normally.
You should still be able to grab them just fine as they have a physics body and the physics scene is auto selected with physical grips, the issue comes in if you let them shatter while holding them, then the body instance is removed and breaks the grip. It needs to be dropped prior to that. (I had a manual check specifically for DM’s in older builds that I had to remove due to its new plugin status).
AFAIK there were no issues with them prior to removing the manual check, except that you will have to manually grip them if you are using the template since I don’t check for them.
Note that destructibles are by default in the async scene, which doesn’t actually interact with anything but static meshes or other async scene objects normally during simulation.
You may want to try passing in the hit bone of the destructible to the grip function (newly supports ).
