I found today one yeti, and then told my guild to come to kill it, but for some including me who had made the most damage did not get the bestiary of it, why would this happened?
The whole story, I found the yeti threw a fire bomb to it, a friend that came with me did the same, then I take it to the left side of the island, I attack it with my hand until its yellow, everyone comes uses a bomb and most of the people got +1 on yetis but for some including me didn't, for some reason my friend got more experience than me even though I had made the most damage.
