The Ancient Offering Sack behind the combination lock door was empty. The quest was previously done by someone else earlier, perhaps the sack did not reset after it was previously done.
i too noticed that this quest doesn't seem to be resetting after completion. Items that are typically found in the containers are missing, presumably not regenerating after a previous run.

It is important to note that this quest can be uncompletable if a certain item doesn't drop from the camp. Even back in the day sometimes those containers would end up being too random, and you either have to go back to town or give up--unless you're already carrying that item around.
Please post any further issues with this quest.
