So to complete the task in the logbook (marin challenge) is only to complete the first task?
By the way im on Plus Version.
no, the task in the logbook won't appear completed because of a bug, but if it weren't for that bug it would technically be complete after beating task two, since there are no further tasks for now. so if you beat the second task, that's it for now even though it's not greyed out
edit: after the update, the logbook entry greys out now after you complete the second challenge!
