When tryin to continue my quest i get a map error loading 9 message. Quest title strategic place occupation. Im not sure if this effects it but i did not kill inferno on the floor above as i managed to click chest without fighting him and got reward and next part of quest fine.

6- Summary:
Every time i click on quest or game decides to auto port me thinking i should be continuing my quest ends up freezing in monster battles and forcing me to refresh every time. I have included a screen shot of the error message to the best i could take as it moves quite fast till it hit first monster and forces me into a fight
