After leeching at Stormbreaker, I was trying to door myself at the map "Crimsonwood Keep: Courtyard" back to Haunted House. I cannot enter the door, neither my friend. Then we tried using nearest town scroll, entering the portals/cash shop/lounge, changing channels, but none of these work. We relogged and I doored again but still the same things happened as above mentioned. As soon as we relog again, we straightly use the nearest town scroll and it works. So I guess bugs appear as you use door skill? For reference, I was launching 800x600 client, not sure if 1024x768 client has the same issue.
The workaround is for the bishop to create the party, and then pass leadership if needed. Happens in the cwk area.
