About half of the time when you complete a mission you don't get credit for it. In a repair mission, you put the item into the machine and both disappear, along with the mission icon and key, but you get no credit for completing the mission. On find item missions you pick the item up but do not get credit for completing the mission. If you put the item back down, then it sometimes just disappears but even if you pick it back then you don't get credit.
Missions are the thing that makes your game unique yet this is the third time you have broken them despite being warned by your testers that it was going to happen.
