I actually noticed this last year, when HOL was having a makeover, but it happened again.
I've written a chapter for collaborative book writing. After a little while it was accepted and I got in my logs 'You won 10 House Points in Collaborative Book Writing.' This I find weird, because when people win points it's always 'X has awarded you 10 points for Class Extra Work/Class Exam/etc.'.
So I decide to wait some time and while I did get the log, no points were counted towards my total. It wasn't just a question of approving points either. Even if points are not approved, they are counted on the main profile, but not in 'House Points' or 'Fact Sheet'.
I never got my points for Getting into Harry Potter story either I think.
Is this another glitch?
