My friend brought a realm for our friends to play on and we have been playing on our realm for a few months now and the more we have played the more laggy the realm has become. When we fought the wither the realm was more or less unplayable and when we use consumables it take our character 3 or 4 attempts before it counts that we used the consumables. When we place water or lava it takes many attempts to pick the water or lava back up. Sometimes when we want to pick up items from off the ground it takes about 4 or 5 seconds to pick up.
