JMMB has an update on the issue preventing progression in the MNOLG. From the BMP Forums:
“Some good news on this issue, it appears to no longer be present. I was trying today to find what Flash Player version was causing the issue, and noticed that today I was able to give Onewa the Kolhii ball and continue on. Perhaps it was a temporary problem with Flash Player. If anyone is still encountering the issue, try reloading the game after the point where it fails.”
If you have had trouble in the past, give it another go and let us know if it works!
