This is new, post latest build. Completed Raid on Ommlet adventure, looted, clicked the shop and the prompt appeared (which it didnt before). I clicked Yes, adventure icon on map shows completed.
ok, this bug keeps moving around. Complete White skull canyon, looted, clicked 'Done' to return to world map and the party adventure cancel prompt appeared again. This time, I click 'no'...went back into the adventure screen of white skull canyon and clicked 'return to map' as 'done' was greyed out. The prompt did not appear again...hmm
