Viridian Wildwood automatically finished

Hi,
today i started Viridian wildwood unique map.
after clearing my equipment in hideout, i came back to the map. When i teleported back, i lost my wisp? (glow thing) around me and map changed status to completed. there was many rare monsters, boss left and idk what more (almost half map unexplored).
edit: i got atlas points from idk :D just dropped after tp back
