Minecraft: Another visit to the Nether and the Portal of Doom

This is another video I made showing my crappy portal that is total fail. In the other video I died at the end and this a few minutes after. The weird part is that my portal in the Nether disappeared, but the obsidian was still there, so I couldn't get back. But the portal was still active in the main world, but this time it created a new portal. I'm sure this is a bug, just like the making of multiple portals when you create just one.
