I am on IOS 12 Public Beta 3 (iPhone 7).. After updating to the latest Junk Jack it has deleted all my worlds and player data..
Update...
after a little tickering.. i found out the folder 3 was renamed to (4).. but with some time this morning i played and found folder (3) was back BUT folder (4) was still there. So tried to pull folder (4) using iTunes. didnt work.. so used Ifunbox and got it to copy folder (4). and look my worlds

.. they do work if i put them into folder (3)..
thought if this happens to someone else they can get back there worlds
