sounds sort of like what I just did with my Bailey (long arm quilter) I put in the bobbin and didn't notice that I bumped one of the latches that hold it all in place - so all of a sudden the bobbin case and shuttle was able to move forward, and the needle came down on top of them. Broke the needle, it did jam a bit but didn't take that much to get free. However I also ended up with a big bur on the very tip of the shuttle hook. Got it polished down and everything is working fine.
My machine came with a spare shuttle hook - because jamming the needle into the shuttle hook is pretty easy to do when you are FMQ.
