Quest Problem

So, yesterday i did the first mission of the Act 2 in hell mode. Killed Radament, but when i did that the sv kicked me off.. So l couldn't pick up the book(to get the extra skill point) and the mission is now finished..
Is there any way to solve this?

 

Try to kill radament onе more time for skill book in own or pub game

 

@karvyy If you didn't take the book and the mission is finished, you only have to recreate the character to get your 12 extra skills... These things usually happen.
