There isn’t a day someone on help channel isn’t asking what to do when he lost the required item such as Scientist to complete the career or epic arc mission.
It seems obvious to me that CCP doesn’t want new players to lose these items considering they are refunding them via support tickets.
So if this is the case, why don’t you make it so these items cannot be lost?
Here is how: in case a ship is destroyed and had an item that is required for current career or SOE epic arc mission, put that item into Redeem Queve and inform player about it. Then the player will be able to retrieve that item back and finish the mission.
This is obviously only for career and SOE epic ark. Failing a normal mission should be possible outcome.
