Bug - Lost Skill Book which gives 2 Skill Points

Hi, i killed the boss Xyclucian, the Chimera with my character PietWonderland (Witchhunter)
The book dropped. As i tryed to pick it up it vanished (as if i had picked it up) but then i checked the inventory i saw my inventory was full to this time. Book was gone, nothing in my inventory and also no skill points gained.

I thought maybe then i do the boss again it will then drop? Even the map sad i "got" my price as the boss was greyed out (still no points added).

So i waited for reset, and killed the boss again, no book drop this time.

So the book is just gone... and i lost 2 skill points thats horrible the character is now doomed. Can you please fix this? And give me my skill points? You can easly check if i am lying, just count the points of the char vs which boss i did and level...

Thx
