I just scored 1140 on dbl yahtzee, and got credit for only 1050...I hate when it tells me to check scoreboard when I haven't finished the game; & then only gives me credit for that part-score.
I rolled 4 yahtzees in today's double-yahtzee game, plus some other good scores, but got no credit for both bonuses, nor for the rolls that got me to the bonus positions: 86 & 71, respectively...should total (w/bonuses)=121 (x2=242) & 106; nor did I get credit for any of the Yahtzees...I wound up with a total of only 192 (I did get credit for 1 bonus Yahtzee in the 'single' line, but no credit for the regular one, nor any of the others.
I too have lost a number of good scores (it shows my score on the leader board before I have finished the game; but fails to show my higher final score.)
