have you added the Deadworld mod??? 
Being an EM collector and having a JD coming soon....what is the Deadworld mod?
What does it do/where is it available to buy etc?
The prototype of JD had a three-ball lock; however due to occasional failure of the mechanism during the testing phase it was changed so that the first two balls were 'virtual' locks and only the third was physically locked.
I think I have that right.
Most JD pinball aficionados believe the gameplay is better with the original locking functionality and so various kits have been developed to restore this.
Start here for an explanation and the original kit:
