I was playing on my friends world and we were in the nether mining glowstone and he died. So he said hey im going to revert it because he saved like 5 minutes ago. So after it was reverted I got back on and I'm above the nether. I was on a fat area of bedrock and you cant place anything so i couldnt make a pillar to jump off of and ****. I tried to walk to the edge of the world and i couldnt even jump of the edge because there is an invisible barrier. Seriously 4J, WTF i can't even jump off and ****. 4J fix this huge bug now. Because now i cant play on this amazing world we were making seriously fix it now.
