I have found a rather annoying glitch in fallout 4. When you go to diamond city and speak to the baseball coach he asks you to find a signed catchers mit and baseball. When I found them I went to return them but the coach wasn't at his stall in diamond city. (day or night) I then marked it on my map and it told me to go to the marina settlement but he wasn't there either? Is there a way to fix this without starting a new game? Also I've completed the "when freedom calls" achievement but it hasn't unlocked but it says 100%.
