Ever since The Division received its first expansion, called Incursion, a glitch that causes daily missions to disappear has kept coming back to haunt the game. Today it's back, and so the daily missions are gone.
On developer Massive Entertainment's official Twitter, they write that they are looking at a permanent solution to this problem: "We are aware that Daily Missions are missing once again today. A permanent solution to this recurring problem is being looked into."
Hopefully for all concerned they can resolve the issue so players can get back to restoring order to the streets of Manhattan.
Thanks, VG247.
