Currently the Nether is experiencing some issue with portals. It will not create a portal in the Nether when you spawn through from the overworld and most problematic, some folks are being put into the lava when they spawn through. I've tested it myself a few times, it seems to be random who is effected by this, so for the first time entering the Nether on a restart, please enter with no items/gear on you. If you run into this issue after that, let me know by hitting the contact button and give me the x, y and z coordinates to your portal in the overworld and when I have a chance I will do my best to check it out.
Thank you so much for your patience while we sort out these things.
