Message From Fortntie Twitter:
The update was short,but gave fans hope of claiming the challenge. Fort the time-being,sticking to the normal battle royale mode would be the best way for the players to get credits for completing the task.Seem some members of community have had success completing the challenge on respawn modes such as Disco Domination. Epic games has go into the problem.
Said By the Developer of Fortnite " In respawn modes, it appears that you will be granted credit until you are eliminated for the first time.After you respawn, you may be unable to progress any further in that match".
