hello mojang team, I'm calling you from bedrock platform latest version 1.17.30, my problem is in 1.17.11 I created several flat worlds and started playing. After a long time, the 1.17.30 version came and I started playing that version. When I opened my previous world, I saw that the blocks I built were empty spaces. Also all the coordinates I went to before were spaces. I've lost many maps I worked for, I'm putting an old and current photo of my world visually, I can't play minecraft because my other worlds will be destroyed too! please help with my problem best regards THEROMANSEN or THE KARA EJDER2
