Electro Post stops working....

I've found myself several times where the electro post just stops working. It even stopped working for the successive games. I ended up quitting the app altogether by killing it and then when I restarted then it started working but also lost all my high scores.

Anyone else seen this issue?

iOS6, iPad 3.

I just love it when the Electro Post just stops working in the middle of a game this time during Harley Multi ball,,... Hmmm did a solenoid burn out? Once again observed this bug.
