After killing camp with enormous ibex,75 frost giant, 35 eagle, 50 bear flood disappiares on the top last area of the map where last bosses are. And all main quests in the quest log have completed automatically. So i have killed only Deer boss in the adventure but the game confirmed me all bosses killing. I run through right side of the map, didn't open center areas. So i have finished the adventure without killing Mammoth, Colossal Eagle, Smilodon and Risi and got normal loot. Also I have got 984.472 exp plus prem (492.236), it looks like normal amount of exp for all i really killed. Has the adventure broken?
