Empty Leader Camp

I killed all the troops in the leader camp but the camp is still there ... the result is I lost more troops then I should have, which means I can't complete "The practical test" quest: "Complete the Secluded Experiments adventure losing fewer than 10 cannoneers." Very frustrating getting so close to finishing the quest and lose it because of a glitch.

UpdateSo I get an email saying that they will give me map fragments so I can do it all over again... really? ...and to add insult to injury I still haven't gotten any map fragments.

Could you drop a nuke on it to see if that clears the camp, or refresh (to make sure your client was in sync with the server)?
