FYI updating to the most recent release of Spigot 1.10 resolved this issue for me.

Gotcha. Well this looks to be something going on with Spigot, then, given that I can't reproduce it with the default JAR. I'll open a ticket with them. Thanks for the help!

So as it happens I ran my server using the vanilla JAR. What happened is that while the problem with Nether Portals did not reproduce I also noted that my Nether world loads completely empty - none of the work that's been done in there was present.

Good question. I'm at work now and will give that a shot during lunch. I'll try and post back in a few hours when I can give it a go.

Bob that's a good question. I do see that message in the server console while falling out of the world but I don't get TP'd upwards to my starting point. I would have to say that it covers part of what I'm seeing as described in MC-103905. However any of that is a consequence of my chief issue that our Nether Portals are now depositing players under the Nether at the incorrect Y coordinates instead of to the proper destination. That's the primary issue at hand for myself.

@unknown Sounds good, I've created MC-103905 for what I'm seeing. It sounds extremely similar and I do know that others have reported the same symptoms of "falling out of the world."

Thanks Fabian, I actually came to this bug by way of MC-89928 which references this one. If you're saying that what I'm describing is a different bug (albeit one with strikingly similar symptoms) should I start a brand new bug report?

Thanks Meri Diana for writing. My world's seed is -2466281547766755436. The Create date on the \World\level.dat file is Feb 28, 2016 so I'm pretty sure we started with 1.9. I run a Spigot server and the only plugin I use is PermissionsEx. If you think it's helpful I can try and load the world using a vanilla server build instead of Spigot.

I went into the Nether in creative mode and had to bust upwards through a wall in the sky of bedrock to get to the nether proper. Once I did I was in the normal Nether area that we're used to seeing. I flew to -5/120/34 (not at all where the Nether portal is) and it's within solid Netherrack for quite a distance in any direction. For reference the actual location of our portal within the Nether is -2/52/-2. There's a structure around it so no fire but one side of the portal is covered by cobblestone.I removed that cobblestone but the problem still persists. I did note too that when I took the portal in the Nether to get back to the normal overworld it sent me roughly (I moved slightly before recording the coords) to -51/38/-49. It put me within solid rock and if I weren't in Creative mode I would have died.

Myself and my sever's players just noticed this problem. We're running 1.10. It seems to either have been introduced with 1.9.x or 1.10. I've tried replacing World files in the Nether but that doesn't help at all. When using a Nether Portal my start coordinates are -5/120/34 and upon going through to the Nether I arrive at -3/-3/-2 (Y value may actually be zero). I appear to be in "The Void" and immediately begin falling from some solid surface, take suffocation damage and die shortly thereafter. Server logs do indeed show "<player name> moved too quickly!" and right after the death message for that player is "<player name> fell out of the world."

I would be happy to provide any files or other data that would help resolve this problem. Right now our Nether Portals are effectively broken in our game.

Two questions: First, is there a workaround for this problem as I've described it? Second, does this affect any new Nether Portals outside the portal-linkage radius (1024 blocks, I think) of the original portals or does this only affect already-existing portals?
