Guild Task Reappearing

What you were expecting to happen, and what actually happened?

Guild Task for 5 Brown Exp, 110 Gold Keys appeared again after it had been completed. Completed it again, gave the Exp but in my mailbox it said that I couldn’t collect reward as I already had earlier. Don’t really care about a refund, just reporting the issue.

Most likely this has occurred due to the server issues we had earlier.
