As many are aware a lot of people complain about missions not being available, specifically metals for the most part
My list of missions is here
The thing people dont realize (or want to realize) is that when you send out a specific type of mission too many times it starts to stop being refreshed in your list. This list of missions popped up after a lot of companion gift missions, the top mission that cant be seen was a moderate fabric one.
This works the same way if i had done only metal missions, i would stop getting metal missions and get more gift/fabric ones
