I logged in today and regd for a game and when the table opened I was marked in yellow and I can't get it off, normally you can't do this to yourself.
Your doomswitch status is on Yellow. Don't worry, you only lose 25% equity on every hand you play. If Red, stop playing at once as you lose 55% equity on every hand thus you will lose all flips and your aces will hold about 30% of the time.
By the way you can even take notes on yourself like "Think before you click"
You did it yourself accidentally. When in hand replayer you can mark yourself and this is what you did. Default note is yellow.
To undo you can simply do the same, no need to go the long route.
End of mystery.
