The 60 SP reward doesn't seem to unlock at 60 SP. Maybe it does at 65, max is 7 at 60 SP. For abyss max stage 70 and 80, I was stuck at 69 and 79 until reaching 71 and 81, so the stat jumped 2 levels; defeating the boss did not give the rewards for reaching next stage.
The 3 inifinite enemies in radiation don't seem to reset their %'s after an infinity. So now I am locked out from all the potential that I got on a different run.
