I'm also having the shooter lane issue. It seems that it veers left as it goes up the fork, slams into the left side, then hits the right wall (a slow motion vid showed me this). I've tried recentering the fork ramp, but it doesn't seem to do anything.
I too was going to try and lift the left side of the ramp to see if that helps first, but that doesn't look like that is the actual solution. I don't have a 3D printer, so I have to find something similar to what our Aussie friend did above and put something on the left wall (essentially making a more narrow path for the ball) and see if that helps. I'm not sure what to use yet, so hoping I can find something...
This is similar to what Rush did on my LE and had to use the inner loop mod fix that NinjaCamp made and put that in the shooter lane and that fixed it (maybe I can reach out to them and see if buying one will fix this as well), but this is worse imo.
Inexcusable that shooter lane issues are now a thing in these new games.
