--- Comment #3 from roidal@googlemail.com --- I found some additional informations in the Backtrace directory of the game. It seems to happen when the game tries to transmit some online-statistics:
-> BBI.Unity.Game.LynxOnlineStatTracking.RecursiveReportOnlineStatistic() fails with: Backtrace.Unity.Model.BacktraceUnhandledException -> [Unity] [Error]: [Online] Auth provider is not authenticated
After disabling transmiting online statistics in the games options it seem to work fine.
