Rof bug Insane xp

I went to forge of souls normal with 2 chars which are connected by recruit a friend ..
with me was a friend with 3 accounts which haven´t RaF ..
at the end of the instance the other guy got 50k xp on his lvl 83 char ..

my connected chars got 4xxk without and 6xxk with level gear ..

so there must be a huge bug with RaF ...
i should get 200% more then the guy without RaF . but its MUUUUCH more then that .

here is the picture of the char with 30% level gear
