If the second ball lands inside the back gutter (rather than bouncing off and landing in the front), the game ends immediately, making it so the game ends while some jugs are midair.
Appears to only happen if the second ball only makes contact with the jugs before falling directly into the gutter. Landing into the gutter after hitting the wall or floor makes the game end normally.
Steps to Reproduce
Throw the second ball in Milk Jug Toss into the back gutter.
What I expected to happen
The game ends after all the jugs stop moving.
What happened
The game ends while some jugs are still in mid-air, causing them to not be registered as knocked down.
