When starting Milk Jug Toss there is a possibility for bottles to move on their own when they are reset into their starting formation.
When moving like this if they land in the scoring area they do not score any points as the player has yet to throw a ball.
Steps to Reproduce
Unfortunately this is not entirely consistent as it stems from a physics issue, but it does seem to be common (at least 1 in every 10 plays or more).
What I expected to happen
The milk jugs should settle into a triangular tower before the player throws a ball.
What happened
Some bottles fall with no player interaction, The game becomes impossible to get a perfect score on as these bottles are not counted for points,
