Missing Maps after Aquatic Update Part 1

After the long awaited Aquatic update, my maps that my friends and I've been working on for the past several months has disappeared, I've tried syncing and I've tried even creating new maps of which nothing shakes old ones back into the menu. I've tried uninstalling and reinstalling the game and clearing data cache etc. nothing. they are just gone, so we just started a new one, but MONTHS of game play and work are gone because of it. Part 2 was rolled out to my console yesterday and no changes on the maps, I was hoping that bug was fixed, but apparently not, so here I am submitting an official bug report.
