Brayflox Longstop - stuck

Just before the 2nd boss is a ramp leading up to a small camp, there are 3 birds there.
On the way back down I jumped off the ledge, when I landed I landed on top of a braizer.
I can not get off of the braizer; jumping, walking, logging out, nothing seems to work. With no way to quit the party, not only have I stuck my character, bit I've ruined the group I was in.

#1 please add the leave party option (it is greyed out)
#2 please look into the braizer issue in Brayflox Longstop

You could have used the return ability, it will teleport you at the begin of the dungeon.
