I found a bug. I got pretty far during eternity. I have over 36 pages of cargo. When i rolled to fire on infinite fleet 30, the game just stood still. Not quite frozen, but no option to shoot or do anything. 
Also, besides that, can you add some kind of rebirth modifier? After getting an absurd amount of boons, op crew, and too much cargo(the game shrieked a lot), it's not possible to lose. This makes something like legacy useless.
