One of the recent updates has messed up the quests on this mini adv.
The first quest doesn't complete after killing the first tower as it used to, somehow the text has been changed and they've added "gain entrance to the creek" and made it a 2 part quest.
Apparently, that refers to the second to last camp, so it sems you're expected to push on with almost the whole adventure without the quests prompting you, then pray it remembers what you've done before and back fill the skipped quests, plus remember to click the 5 hidden objects before finishing the adv.
