Hi David, Only found two stones in Ocean Spire, so went off to Matani for a break. When I left Matani to go to Cacophony it crashed. I tried going from Mountain Spire and Ocean Spire to Cacophony but it still crashed (so I have two more crash reports). Then I tried going from Mountain Spire to Boulder Reef, then Boulder Reef to Cacophony. That worked so I was able to carry on playing (and found all the stones).
I hope that helps. Please let me know if you need any more info.
Thanks,
John
