Just set up my Hobbit and am finding a minor issue with the left VUK under Smaug. When it fires the ball reaches the end of the VUK wireform, hits the end of the horizontal section and then bounces back the way it came and down to only be fired back up again. This may happen 2 or 3 times before the ball is successfully deposited in the main left wireform.
Has anyone else experienced this? I'm thinking that reducing the power of the VUK may be the solution and will post back here if it is.
