Didnt drop the passive skill book from cruel 2 boss Kabala while teaming up with a friend

Didnt drop the 2 skill point drop from cruel 2 boss Kabala
I was team up with a friend and the boss dropped the passive skill book for him but not me.
I am certainly its the first time I kill this boss because we process the game together. Please fix this bug and give me back the skill book T-T.
2 skill points are very important in this game.
Thank you
Jason

Hi!

Same problem with Kabala but solo

I had this problem as well on beating her on cruel by myself.

disregard found in the titans extra stash...
