Long story short I had 1 completed mission, 1 mission I completed during the game and 1 mission I was saving.
After the game ended and I completed that 2nd mission, I only had 1 mission available to do and it said the game would reset in 2:58 minutes. It didn’t give me a new mission for the one I completed hours earlier nor for the one I completed mid-game.
I tried restarting my game and playing another mode, missions did not appear.
