I created my personal portal a while ago, and it worked perfectly normal until tonight, when Heralen, TigerAbyss, and I went through and found that we were stuck on top of the bedrock roof layer of the nether. With the help of Conathan, we were able to get out, and we continued to experiment to make it work by transporting the portal somewhere else and such. It didn't work. Is there any way to fix this?

build a base up there? *smirks* seriously though that's a wierd one.

Lol I think it's a bug where ur portal is spawning in a wall and to stop people suffocating I think it /tops u I'm not sure tho . I used to (last year) suffocate myself with sand blocks then relog so I was on top of the nether . (it doesn't work nowadays so don't u be trying it lol)
