Bug Ball stuck, seems to be floating

I've encounterd another strange bug on Ripley's. After I had the 'right ramp lock' bug as mentioned here by ND3G: http://digitalpinballfans.com/showthread.php/117-Right-Ramp-Lock, I was able to get the game going again using the 'call attendent' option but the table then completely lost track of what was going on. It sent 2 balls from the multiball lock into play when it shouldn't have and after I lost one of them, the other got stuck on the bottom left and seemed to be floating (see screenshot). It might be because the game thought only one ball was in play.

I had that issue on a seperate ocassion, but it was higher up the slide. I emailed Farsight and said they would try to recreate the issue. That was shortly after launch so hopefully it will be fixed in the next update.

It happened during multi-ball.
