Sometimes I get rock points even though my selection is scissors or paper.
W/T/L is displayed as W/L/T.
Streak sometimes goes up by 2, or mulligan drops by 2.
I have long suspected that rock points are disproportionately higher for some reason, but I haven't figured out why. I will investigate this one more.
EDIT: Found the extra rock wins bug. Error in my random logic.
The W/T/L was wrong. Will fix this in the next release.
The streak going up by multiple is likely from an upgrade (will double check), but I have not seen mulligans dropping by 2. I will see if I can repro this.
Looks like one problem with mulligans is that if a match loses a mulligan every match below it also loses a mulligan. So if you have 6 matches and you get l,w,l,w,w,w your mulligans go -1,-1,-2,-2,-2,-2 instead of -1,0,-1,0,0,0.
Even then, there's more mulligan losses around, haven't seen the exact pattern yet.
The weirdness is very visible when rocks don't lose and paper and scissor are 50-75% switched to rock. So there's only 0-1 losses per round.
