Unable to continue with adventure quest

[HeroOfCanton13]

I recently started playing adventure mode and I ran across an issue with the Dig Site quest. I had already cleared the site before I received the quest to do so. I am now unable to complete the quest. Is there a way to reset the site or mark the quest as complete so I can move on? Additionally, something should be done to prevent this issue in the future, maybe not creating the site until the quest directs you there or just resetting it as soon as the quest is received. It probably wouldn't be an issue too often as it likely isn't common for someone to come across the site and clear it out before directed to by the quest as I did, but as I am proof that it happens.
