OK I seem to have gotten it fixed for now. I just didn't tighten the bottom plate on as hard. I was thinking if maybe I put a bit weaker coil on that assembly that it wouldn't happen anymore. Right now that coil is kicking up the targets harder then it really needs to, I think if I replaced it with a weaker coil it wouldn't cause the jamming anymore?
I played a good 30 games or so after I put that bottom plate back on and so far so good, but I think the a bit weaker coil may fix the problem for good...
