[MC-90026] Elytra flight desync when flying into unloaded chunks

When I teleported to a friend while gliding with the Elytra, the game acted like I was still in glide mode. When I jumped, I moved forward without pressing any buttons, slowly moved forwards when not moving, and could not cancel by jumping off of tall heights. I stopped the glide by doing a creative mode fly, but it then disabled glide mode completely and didn't fix until I died.

To reproduce: Fly out of loaded chunks, then teleport to a friend (they might need to be on the ground). You should be in hover mode while on the ground.

TL;DR: Glide into unloaded chunks and teleport to a friend to get stuck in glide mode until death.

From MC-90834:

To reproduce:
1. Go to a high place, preferably y:255
2. Start gliding with an Elytra, go forwards at a small angle towards the ground so you accelerate
3. When the world around you isn't loaded, let yourself glide to ground level, y:64
4. When the chunk loading catches up, you'll be stuck in flight mode

Same here, it occured while I was playing McMakistein's minigame. I can still fly around, the game is even trying to fly while I'm walking. That video demonstrates the bug: https://youtu.be/5l0njrG49Wo

Noah Larkin 2015-10-08T21:45:51Z

And some more video proof, even though some has already been provided by the guy above. (also, thanks for the video footage, it's much better than a screenshot)

I had this bug too, It was a single player world and I flew into an unloaded chunk and after that, I couldn't land. I assumed it was because I added feather falling

Swekob 2015-10-26T13:01:14Z

Confirmed for 15w43c.

Swekob 2015-10-28T19:31:30Z

Confirmed for 15w44a.
_{This bug is hilarious by the way!}

Confirmed for 15w45a. (Seems to have been made harder though, and occasionally teleporting far away disables the Elytra completely.)

Edit: By harder, I mean a LOT harder.

Swekob 2015-11-07T22:12:10Z

@unknown: That's MC-89994.

Swekob 2015-11-12T15:51:21Z

Confirmed for 15w46a

Noah Larkin 2015-11-19T02:33:48Z

Still possible in 15w47a, but pretty hard on laggy computers/USB sticks. (Either that or I was /fill'ing dirt before I started gliding... yeah, that's probably it.)

Noah Larkin 2015-12-02T23:17:27Z

Haven't been able to reproduce yet in 15w49a. World loads before player starts falling when teleporting and is hard to recreate on laggy and good computers. You'd need a medium speed computer or something. It might also have been fixed by another fix or something, I dunno.

tomudding 2015-12-18T14:29:52Z

Can confirm for 15w51b, as Noah Larkin mentions the best way to reproduce is using a medium "speed" pc.

Hans5958 2015-12-19T05:02:13Z

Lagging PC should can reproduce this. (like mine)

tomudding 2015-12-19T08:22:59Z

I used a good PC and I am still able to reproduce this. It is about how you render new chunks.

Noah Larkin 2016-01-15T12:14:27Z

I still sadly haven't been able to reproduce this on the latest version (16w02a). Teleporting basically freezes me and then makes my Elytra never activate. Can someone else test?

Stryker 2016-02-24T15:21:00Z

Have not been able to reproduce in 1.9 pre2

user-f2760 2016-02-24T15:54:39Z

anybody still able to reproduce?

Noah Larkin 2016-02-27T12:36:42Z

MC-89994 seems to be 'fixing' this bug, but if that gets fixed, then this will most likely be possible again.

FaRo1 2016-04-24T22:25:16Z

What does "is blocked by" mean in the issue link list?

user-f2760 2016-04-24T23:25:56Z

Blocked by means it is "fixed" by a different bug, in this case, it was MC-89994, but it got merged, along with others, in MC-92916.

Torabi 2016-04-25T12:24:07Z

Blocked by means that it is caused by another bug, or cannot be fixed until that other bug is fixed.

wobst.michael 2016-10-23T18:28:22Z

Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w42a) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time. If you are the owner/reporter of this ticket, you can modify the affected version(s) yourself.

FaRo1 2016-10-23T19:54:25Z

Yes, but it's a duplicate of MC-92916, not blocked, I think.

MasterOfTheTiger 2016-12-19T01:26:20Z

16w50a too, and fireworks stop working with Elytra when this bug occurs

Andrew H 2016-12-22T20:07:15Z

I've noticed this glitch too. It can happen when you die by firework blast or "experience kinetic energy". Once you die, you will respawn already in glide mode. Once this has happened, you can then take off your elytra and still glide, but you still take normal fall damage once you land. Another way to cancel it is to use your the Control/Sprint button while you are "walking" on the ground.

Confirmed for 1.11.2.

Owen Knox 2017-03-30T23:09:24Z

Something similar to this, but slamming the ground (any chunks, unloaded and loaded) in 17w13a does the same thing. Stuck in flight mode, various results ranging from seeing through walls to odd movement.

[Mod]Les3awe 2017-05-18T16:30:43Z

This issue still occurred in the latest Minecraft version?
Because of MC-92916 has been fixed in 1.12 Pre-Release 3.

Jack 2017-06-24T10:51:17Z

yes and its easily doable in survival. just jump into endgateway/exitendportal while in flightmode and you get into permanent elytra flybug.can take elytra off but will stay in elytramode.(super high jumps,gliding on the floor,hitboxchange, rockets dont work?)

Caden Thomas Schroeder 2018-10-28T16:08:20Z

I experienced the same kind of issue after dying due to using explosive rockets. For some reason it stopped whenever I drank a potion, and when it was in action my friend just saw me moving sluggishly on his screen.

user-f2760 2019-01-11T00:34:56Z

I experienced this issue in 18w50a once, might want to add it.

Greg Creswell 2020-04-18T01:38:26Z

I am experiencing this issue in my version of Minecraft. I just got Elytra and now even if I unequip it I have super jump. I don't want to die and lose my elytra. How does this get fixed?

Avoma 2021-12-30T17:01:55Z

Can confirm in 1.18.1. This doesn't happen all the time but this issue is still present.

Avoma 2022-06-20T16:47:04Z

Can confirm in 1.19 and 22w24a.

whyAnton 2024-05-26T02:07:20Z

im pretty sure this happened to me when i used a riptide trident with an elytra when i was going too fast into unloaded chunks
