You get 10 Influence and 5 glory after every sucessful mission, but you get 10 Influence too after every failed or abandoned mission.
so you can get easy 800 influence to get System Rank 5.
but when you got a system with item rewad in the end, your game is completly unplayable cause you start a mission until you accept the item reward.
And when you click on the Reward you got a Game crash, but the Reward isnt claimed so you never can start a mission again
New charakter doesnt help he get the same Reward button
