Our Hobbit machine in Kfar Saba, Israel, has started to get major issues. Wasn't upgraded to the latest code because of the computer specs there (A motherboard should be replaced for that). One of the pop up targets doesn't rise, some of them don't detect hits or hits are registered randomly, and the DWARF Drop targets are sunken on their right (This causes the "F" target to rise for a millisecond and to drop immediately)... The kickback sometimes works (A problem that this machine had out of the box). Right flipper sometimes gets stuck. Any tips on fixing those? I will send those tips to the machine owners.
