map problem Upper Hadar in Dwarf land

[khanhdx]

Hi guy am new here. but here my problem, in Upper Hadar I tried to do the quest "Tame Hayena". After i finishing the quest and tried to get the reward, i could not click on the drawf house to finish the quest. But worst of all i couldnt interacted with the whole Upper Hadar. which mean i couldnt finish to get Lina as my Rage unit by touch the machine, i couldnt talk to the npc or interact anything in the map, the only thing i can do is attack creep and pick up item. Before i didnt finish the Tame Hayena i still could click on the house. all the other map work fine but except for Upper Hadar. so that all i have. thank for reading and HElp
