My inventory keeps wiping on Bedrock. I lost a bunch of enchanted items I spent hours on trying to get. I was forced to go creative to get them back, and now my world is permanently in that mode. I've spent maybe 20 hours on this world with my friends so far and this is very upsetting. It's happened before, but this one hits harder because I lost much more important items.

Edit 1: I should probably clarify that it doesn't only happen with multiplayer. This happens when I save/quit or leave for another app and come back later.
