Worlds randomly Reset

As soon as 1.11 came for Bedrock, the Wandering Trader map came out, i first experienced the glitch on this map. When you open one of your worlds, there seems to be a chance that the world will just RESET. You lose all your builds and how the world was changed, you lose the items on you, but for some reason, the time of day remains how it was before the glitch occurs. At first i thought it was just the Wandering Trader map, but then i opened my best Survival World, and i lost everything. The worlds also regenerate, so there was now a 1.14 village at spawn. I had a big two story mansion on that world, and now i will never get it back. Im thinking of quitting until this glitch is fixed.
