Grampie43: Twice now, our friends at WGT have snatched my last ball, and have not given me the opportunity to finish the game with my preferred balls.
You'd only get a message if the last ball in use is available in the Pro Shop.
OTOH, due to changes in the "last ball" reporting, there are flaws in the game giving unneccessary or wrong information or omitting neccessary information - from former experience, the time they'd need to fix'em is unpredictable.
Thus, it's good to keep an eye on the ball number.
Grampie43: Also, I had better balls of different types in my bag that are better than starters,
Wrong, Sir! Only one type of balls is in your golfbag, the others are in your garage - ehm - inventory.
