I'm not sure why exactly, but OP can confirm / elaborate, but he removed the bolt completely and then started the engine and moved the car after lowering it from the jack stands, and moving the car onto the ramps for better access. I'll go back and read to confirm.
^ This is how the damage happened.
As an experienced tech, and an enthusiast who has messed with the dogbone mount multiple times, I didn't know doing this would cause the issue it did, so while it seems /palmface worthy in hindsight, its not something that would cross your mind at first as a possible issue.
After seeing the damage and doing a visual inspection it makes sense, just surprising.
There's a fairly decent chance that when he moved the car, he accidentally pulled the metal portion out of the subframe enough so that the bolt could stick in behind it. It probably would still wheel hop less as the engine mounts would be bound up due to the the amount of twist on the motor. That amount of damage is not something that could be created in a very short time.
