No Stars for two or less at Campaign Stage 8 - 5 Nightmare.
I set a goal of doing one part stage a day. After a few weeks it dawned on me I had not progressed. Well I kept banging at the door and still no "3 Stars" for stage 8 - 5 Nightmare. On looking at the screen, for once, I noticed the three stars are blank in 8 - 5 Nightmare. Why is this?
