Hi, I have a survival minehut server that a friend and I play on. I was in the nether and I was teleported down to the bottom bedrock layer of the nether, this happened once but I mined the netherack around me and made a tunnel under the lava lake till I got out. This just now has happened again I was on a 2 block tall pillar farming zombie pimen when I accidently jumped of, i ran around, tried to jump back onto my pillar but was knocked off, I was teleported but this time I was in the bedrock suffocating. I only have the WorldEdit plugin and am currently using optifine - 1.16.5 Thank You for any help
