Nether portals don't generate or generate unlit

New as of 14w28a: The first portal you create in a world has a small chance of spawning you underneath the bedrock of the nether in the void, spawning you in a wall, and generating the portal unlit. After this, any newly created portal in the overworld automatically links to the original portal in the nether, no matter how far away.

Updated steps to reproduce:
1. Create a nether portal in the overworld and travel through it, preferably in creative due to the chance of spawning in the void, spawning in lava or suffocating to death. Remember your surroundings when you enter the nether.
2. Re-enter the overworld and create another portal any distance away from the original and travel through it. You should be in the exact same place as before.

The photo I attached from my phone was to replicate the issue I had run into in a freshly generated world, just in case something was broken from an earlier snapshot.
Importantly, it gives you all the details to replicate this bug yourself:
1. Create new creative world with seed: 529770237
This is the same as the seed: New Features
2. /tp -638 63 44 83 19
(Facing a really nice cliff over water, with a waterfall, lavafall, and stone pillar.)
3. Build a nether portal, light it, and travel
4. You were in Creative mode, right? If not, you are now dead. If so, you will not find a nether portal, at least I didn't digging around in the nether rack a lot.

Mateo Hernandez

Yes, I was in creative mode.

Sebastian Moschke

For me the portal in the Nether spawned above a lava lake and I spawned inside the blocks I was supposed to be standing on, thus took suffocation damage and fell into the lava lake.

Brad Johnson

This bug does not seem to be fixed. I am running snapshot 14w26c and the description of this bug consistently happens whenever a new portal is generated. Once the portal is generated, usually traveling through it works fine. Although a second unlit portal may sometimes be generated.

Reopened
Has been reported again repeadetly, also with new effects.

I've confirmed in my game that it creates a variety of portals, sometimes near each other, all unlit. Sometimes you materialize in dirt or stone nearby and beneath the portals. Other times, if you lit the portal yourself, it will direct you there reliably. When snapshots are turned off and the same world is created in vanilla Minecraft, portals generate normally in the same locations.

Christopher Carrig

Pictured are the region where unlit portals keep spawning and the location underground where I was placed at least twice when one of the portals was generated unlit.

Jens Grotholtmann

Confirmed. I fall through the ground and burned in lava or stuck in the ground of the overworld. Bug "works" bidirectional.

Jaqi Hegland

Happened to me today. I was in some solid block, pitch black and unable to place a torch, and when I died, my screen said, "Puzzlemage fell out of the world".

When I respawned and went through the same portal again, I was back in the netherrack, but I could see it this time. I could NOT break the netherrack, there was no hitting animation, and with no portal I could do nothing. I died again. When I was there the second time, my equipment was not present.

Original Report: MC-61823
OS: Windows 7 Ultimate (64bit)
Java: Java 7 Update 55 (64bit)
Game Mode: Creative

I created 10 worlds today and went to the Nether in Creative Mode.
I only experienced the problems mentioned in this bug report in two of the worlds.

Incident #1:
Entered Nether inside Netherrack.
Was able to break surrounding Netherrack with pickaxe, otherwise I would have suffocated.
Was able to use my pickaxe to go to the surface of the Nether.
There I found my Nether Portal. It was unlit.
Reactivated the Nether Portal and was transported back to correct Nether Portal in overworld.

Incident #2:
Entered Nether underneath a body of lava.
Was able to get to the surface and swim to shore.
The Nether Portal was on the shore It was unlit.
Reactivated the Nether Portal and was transported back to correct Nether Portal in overworld.

Dustin A Mundy

Happened 3 times in a row to me.

Portal issues seen in a world with several existing portals in 14w29b:

1) Some existing portals no longer lit, both in the overworld and nether.
2) Some existing portals partially lit (one blot lit, all blocks but one lit), both in overworld and nether.
3) Going through portal landed in mid-air in the nether, falling on top of existing portal. No new portal.
4) Going through portal into nether and landing over lava (ouch). Returned to find new portal (unlit) about 6 meters from intended (also unlit) destination had been created on shore of lava ocean near where I fell.
5) Going through portal back into overworld and materializing in solid rock. Dug to surface to find second unlit portal about 6 meters from my intended destination (which was also unlit).
6) in a couple of cases, portals were entirely lit and functioned normally.

In all cases, making sure the portals on BOTH ends were completely lit by destroying any portal blocks in creative and re-lighting resulted in the portals working as expected. This suggests to me that portal coordinates were corrupted but that re-lighting the portal stored the coordinates correctly.

This was already fixed in the most recent snapshots

Roadsguy

Was this the cause of Etho's portal teleporting him thousands of blocks away in one of his recent LP episodes?

Tokes

Probably not. That portal worked but multiplied by 64 instead of 8. And he emerged from the lit portal, not elsewhere below or above it.
