This time it's more seriuos.
Lost a ball on the water hazard while playing a RG event, unfortunately was my last Nike in the bag so I buy from the pop up mask a new sleeve. The sleeve was added in the bag but the pop up mask keep loading without give the chance to the player to join back the game.
After closing your browser page and If you try to restart from the saved game you will have the chance to keep playing with a standard one in a Ready Go event or buy a new sleeve, but the issue won't leave you and it will give you back, once again, the same loading mask.
