You do realize that balls have a DURABILITY index, they don't last forever like the Unlimited ones.
If your shot was OOB then you would have had an extra stroke added and have to hit from the tee again.
since you didn't mention this I am guessing it wasn't OOB.
there is a little bar next to your ball that tells you how long your ball will last
When it disappears your ball is taken out of play
