it was always round numbers like 2.80 or 1.60 , and today all my kepe with numbers like 1.39 or 2.79 how >?>

Also my paragon hp points from 2 to 1.9

My 2s turned into 1.9 on paragon too for some reason

That's strange, can't say i've noticed that myself. I have no idea what could cause that, maybe something in the latest patch that's messed with coding a little and it's 1.9999999999 but showing as 1.9 maybe. I'd submit a bug report and see if it gets fixed soon.
