Besides the new "last shot, buy balls" pop-up coming prematurly, the well-known "last ball" message is still there...

... with some changes:
- it's bigger than before,
- it doesn't disappear by itself after some seconds,
- it disappears when the meter is risen, and it re-appears when it's let go without a shot,
- when re-appearing, it's broken, as you see in the pic.
I didn't take a shot, so I don't know if it re-appears on the next shot(?)
One problem when provoking to get it is, you must use a single ball from your inventory which is on sale in the Pro Shop. Otherways, the "Buy Now" button wouldn't work, thus the program will not show the pic. I've been using the "Bandon Dunes" ball.
