Summary: Ammo icon shows for out of mission groupmember
 
Description: The field supplier icon shows for the people in the mission when a groupmember that is not in the mission uses his field supplier.
 
Steps to reproduce:
 - 1: Join a group
 - 2: Start a mission, with opposition
 - 3: Have someone else join the group (or have them join the district if they're already in the group)

 - 4: Have the newly added person use their field supplier (default is 5)
 
How many times have you recreated this bug: 1/1 (I've seen it before though)
