Hi all, I have a Munsters Premium and having an issue where the Grandpa VUK is ejecting the ball straight down the middle. This is normally aimed at the left flipper, but started migrating to center of the flippers and very quickly has become unplayable. There are some flaps/guides in the grandpa hole which I've tried to adjust, but any fix is quite temporary and typically only solves the problem for 5-10 ejections and then it's back to SDTM. Anyone with advice? I've dropped an email to Stern but no response in a couple of days.
