I have a portal in the over world, that leads me to the Nether. This specific portal is located over lava in the Nether. When I go through the portal, the portal will drop me inside the lava. I have tried putting blocks underneath the portal to stop me from going into the Lava. But after I did that, it started spawning me inside the blocks causing me to suffocate and die. I have had no problems with the portal until today.
