Re: can't play gnome bomb

Hi, Gnome Bomb won't load any map - just a blank screen with the flower in the lower right.  This is on a PS4 with GW disk (purchased new over a year ago).  Problem started recently but all other GW game modes work as expected.  Other game titles work.  Rebooted several times and also checked for updates.  Disk appears clean.  I'm debating if the only solution is to purchase another disk or purchase the downloadable game.  Is that recommended?  Thanks.
