I Am Stuck In The Nether And Can Not Access My World As The Nether Portals Will Not Let Me Go Through Dimensions. Also When I Try Going Through Dimensions Plays A Loud Unusual Sound That Isn't A Official Minecraft  Sound. As That Happens I Get A Text In The Box That Reads "Get Out!" This Can Not Be Through A Player Trolling As My Mullite Player Is  Off. My World Also Lags Way To Much And My Internet Is Fine , And My World Could Not Be Lag As It Is Just A Natural Spawn Of The Sunflower Biome
