Help Needed: Game of Thrones generating bugs

I need some assistance to track down a bug that appears to occur almost exclusively in the Game of Thrones module. No-one using this module seems to be adding their email address to the bug reports, so I cannot contact anyone.

The bug reports shows a NullPointerException in StackMetrics,Merge().

I need a log file that recreates this bug so I can nail it once and for all.
