There's an issue with the OCTGN sets in my download area. They seem to be conflicting with the Foundations of Stone set which can cause problems if you have included any player cards from FoS. I am working on a fix and it should be available in the next few days. Sorry for the problem.
The OCTGN issue has now been fixed and the bugged .o8s file in my Skydrive has been replaced with a working version. You should make sure you delete any copies you have of the old version and also uninstall the old .o8s file from OCTGN before you download the new one. Sorry for the problems, I hope you enjoy the game!
