I have searched, can't find this exact issue. I do not have a converted world, heavy redstone builds or any normal game lagging/crashing entities near by. Happens on xbox one and less often on the win 10. Should note I am playing on a Realm, at the time I was the only one on. Doesn't seem to have a specific trigger or time frame. Example I was working on the nether hub yesterday placing and breaking concreate and glass and it would randomly crash. Sometimes it was after 10 blocks sometimes it was 200 blocks. A few days ago building in the overworld building a barn it hard crashed my xbox and soft crashed my computer
