No worries, but yea I agree, it seems to be some sort of physics bug, it doesn’t seem like anything in the code would be affect it but maybe just after releasing if the body is slightly through the ground it falls through. To test you could maybe do a line trace from above the actor a bit to the floor when ending the grab, and then set the actor location to be maybe 20 units above the hit location.
Also test out a few different print strings with you “Get” nodes just to double check none of them are failing.
