Has happened twice now...
Both times on SA #1... first time was during practice round... last instance was during the current single-play 18hole.
Clicked on my 60W to change it from the caddy-chosen 54W for a <75yd approach shot to the 1st green... screen went white and then WGT reloaded. During the single-play tourney, the option to continue pop-up appeared after the reload.
Tried to submit in-game bug report after selecting "continue", but it hanged and I had to cancel it to continue my round. Gameplay then continued normally.
