When playing a daily mission on hard difficulty, the daily mission-specific rewards are not received after completing the mission. Only the usual rewards for a hard difficulty mission are received. In the attached video, the rewards for completing a daily mission (Capitol Building in this case) are 449550 XP. However, only the 182575 XP for replaying the mission on hard difficulty are awarded. In instances where the hard difficulty daily mission reward is an exotic cache (not shown here), the cache is also not awarded.
