Had the same problem on Xbox one version 1.2.13. Items and mobs all disappear when I approach on the forth block between us, so if there was only 3 blocks between us. Creepers still explode and do damage but I can’t hit them because they explode. Can’t interact with mobs but they still make sound. I could get items if they flowed in water but if I moved to them, whether it was stationary or flowing, they disappeared and I couldn’t pick them up. If I moved away they reappeared. Had four users on at the same time in the same console when it happened and the problem persisted when we turned the Xbox off (in the regular quick start mode) and only one player came back on. Problem resolved when I did a hard reboot on the console by holding the power button for 10 seconds. Hope that helps.
