[Server Issues] One legendary task can be collected several times

Nintendo Switch platform

some of our guild members received the same legendary task more than one time.
As you can see from the image, this is only one legendary task but can be collected several times.
Some of our members have already collected those rewards by accident, I hope that won’t cause any problems for their account.

Thanks.

Hello AliceTong! Could you please let us know roughly when this occurred? We experienced some server issues which may have caused this.

Hi Saltypatra, it happened around 16:00 GMT.

Thank you for getting back to me! This happened due to server issues and is not a bug within tasks. We are looking into it further.
