Major Chunk Errors

Ever since the official launch of the nether update for bedrock, our realm as been experiencing major chunk errors. The realm is played on almost daily. The chunk errors have removed everything in its area, and replaced it with natural spawn. When noticed, we reset to a previous backup, and although it saved our builds, we still have many errors, including straight up chunk errors that if you fall into, you fall through the world and die. It's happening in both the nether, and the overworld.
