This isn't the first time this has happened. So a bit of backstory, me and my friend like to play Minecraft a lot, she doesn't have a PC so she uses the Bedrock version and since I had the Bedrock Edition, I played with her. These "corruptions" happened at random times but the thing that was consistent, was that it happened when you left or joined. And when I mean everything, I mean everything. Spawn point, gone. Inventory items, gone. I haven't checked Ender chests, but today was the 2nd time it happened. Idk why this keeps happening but due to the corruption, I lost a lot of things in our world that we had worked on for 2-3 months. The first time it happened, it wasn't a big deal cause I didn't have a lot. The 2nd time, today, I had many things. Diamond items, enchanted items, all of it, gone. I don't want to re-enable cheats because me and my friend wanted to beat the game without any cheats. Please fix this issue or something, I don't want this to happen again. Btw, this happened on 1.16 and 1.15
