Hello. Thanks for contacting us. Players must successfully complete all encounters of the Root of Nightmares Raid during the contest mode window and claim the associated Horticulturist Triumph in order to earn the "A Good Night's Sleep" emblem reward. If the Triumph was not earned and claimed, players do not qualify for the emblem. While players may appear to defeat Nezarec, part of the challenge was to complete the encounter itself, too, which includes the wipe mechanic. Teams who died to the wipe mechanic before they were able to fully defeat Nezarec would result in an unsuccessful clear.  Additionally, factors such as poor connection, joining raids in progress, or not successfully receiving rewards for all encounters may have contributed to completion ineligibility.
