Over the limit

It seems there is no system in place for selling extra champions if you are over the limit on the field. If your bench is full your carousel pick will go to your board and if your above the limit and the round starts you now have an extra person.

I haven't tested it any more than I picked someone and couldn't decide who i wanted to sell and ran out of time and died that round.

Don't know if other people have come across this but i'm sure this isn't a "Feature"
