Over the last few months I have noticed this problem. I currently have the replay in the settings at 1,700,000 and to award an extra ball. It was fine for a couple of weeks but now on the display it says extra ball at 5,000,000. In the settings it still says 1,700,000 but it won't award a ball at that amount. It's been like this for a while and the only way I can get it working properly again is to completely change the number in the settings. Then it will work for a couple weeks and go to some huge number again. Some of my other machines automatically adjust the replay amount but it's very rare and usually goes up only a small amount. I don't think that's happening here. I have had this machine over five years and for all but the last few months it had never done this. Any ideas? Thanks in advance.
