Kills are counted double in quests and Book of Knowledge progress
When on the Tutorial quest "Wolf Hunting" it looks like most of the young wolfs I kill are counted double.
Same thing with the Tutorial quest "Quest For Knowledge" where the black bears are also counted double.
Not all of them but a wast majority were counted double.
This is both in the quest and Book of Knowledge progress.
Not sure if this is limited to just some beasts and enemies or if it affects all.
I have not hunted much with the current char I am testing and the rest of my chars have mostly 100% knowledge so can't test with them.
Not sure if this is a new bug in A2.2.1d.
