I was doing the dark harvest event, i was killing the last two event monsters when one of them hit me and pushed me in a place otherwise inaccessible so i was stuck there, i have a screenshot but i don't know how to put it here help? I can't reset the mission cause of the restriction
I am assuming by this time that you have resolved this, but just in case you come into this issue again you can file a bug report by pressing F2 and listing your reason. I am not sure nowadays, but usually a Game Master will come to help you in 15min to 1 hour depending on the time of day.
Hope this helped.
