@ubiwan I was playing the game earlier today and found out my save file was corrupted. I lost only an hour of game play but when I loaded the game up again the quests were back in my quest log. I was able to complete the quests without an issue.

I was playing on my Xbox one. I am about 19 hours into the game and I pre-ordered the game before it came out. I had already looked at the letter in the longhouse to get the mission added to my quest log and for a while it stayed in my quest log. I was holding off on starting the quest until I was a bit stronger. I went to find the quest start point because I was ready to play the quest and it wasn't in my quest log. I tried power cycling my Xbox (turn off and unplug for 30 seconds) and I tried uninstalling and reinstalling the missions to no effect. When I look at the game in my system I can see the pre-order missions installed but they aren't showing up when I load up the game.
