Some of The Division's daily missions are outright gone. According to Ubisoft, something went wrong and they will be fixing the issue in the next update.
Apparently, the Hard and Challenging daily missions did not reset properly on April 9 and Ubisoft didn't really seem to know why. They still don't seem to know what spurred the issue, but they have stated that this problem will be fixed in the next update which comes out April 12.
Until then, players will have to skip out on the Hard and Challenging dailies.
Please note that the issue with Daily Hard and Challenging missions will be fixed with the Update deployed on April 12. 1/2

Some The Division players asked if they would get some compensation for this inconvenience, but the Ubisoft Support on Twitter said that they have "no information on compensation at this time".
