[MC-101563] Switching from Spectator to Survival causes player death by fall from low height

Switching from Spectator to Survival causes player death by fall from low height

What I expected to happen was...:
When three or four blocks above ground (not water), switching from spectator mode to survival mode, I should drop to the ground with no or minimal damage.

What actually happened was...:
Death by fall

Steps to Reproduce:
1. Not sure yet as the problem is intermittent. Generally flying around in spectator mode, above and below ground then moving to a previously visited area and switching to survival mode triggers the bug. Will need to do more research once my wife returns home. This happens to her occasionally, but not to me. She is running vanilla 1.9.2, but I believe it also happens in previous 1.9 versions and 1.8.9.

Just happened on Realms in a new 1.13 world. Wishing I had started recording. Drop was 3 blocks.

More information: I load a single player game and open to lan. My wife is having the problem when connected to the lan game. I, as the host, am not having this problem. Her work around is to always return to survival over water.

Cannot reproduce in 16w43a.

Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w43a) 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.

Michael 2016-10-29T23:24:47Z

Yes, this has happened in 1.10.2 and 16w41a. It only happens when she is a client on my Open to Lan game. We have not loaded 16w43a (or 42a) yet, so I cannot confirm that it happens there.

Happened tonight on our Realms game in 1.11.2. From spectator mode to survival at a height of 3 above the floor.

You take damage as you fall to the ground, more than 3 blocks is the limit when you start taking damage.

Might be WAI

Urielsalis,
She was at full health and dropped 3 after returning from Spectator to Survival. She could not have dropped 4 as the space she appeared in was underground and only 5 tall.

Uriel Salischiker 2017-03-26T17:04:29Z

But did she die from the 3 block tall fall or she only took some damage(half a heart from 3 blocks iirc)?

Michael 2017-04-06T16:44:57Z

She was at full health when she made the change to Spectator to Survival and died from the 3 block fall.

– Additionally, she was wearing full enchanted diamond armor with Feather Falling IV on her boots. Previous times in previous versions she did not have feather falling.

Uriel Salischiker 2017-04-06T19:59:13Z

You can recreate it easily or it happened just once? Does it happen in the newest snapshot?

Michael 2017-04-07T03:43:40Z

Unfortunately (or fortunately) it only happens rarely. It has happened in every version since 1.8, including 1.11.2 and the 1.11 snapshots. We have not played enough Open to Lan games with transitions from spectator to survival in the current snapshot to trigger the death.

Uriel Salischiker 2017-04-07T20:25:30Z

can you try recording a video and trying to do it multiple times? So we can have it in video if it happens?

Michael 2017-04-07T21:30:59Z

Do you have a recommendation for a safe, secure, and free video recording software package? This may take several weeks to capture.

pokechu22 2017-04-07T22:41:52Z

OBS is what I'd recommend; you can record to file from it (though it defaults to streaming).

Michael 2017-04-08T04:39:46Z

Thank you. Downloaded and installed. Will do some testing this weekend.

Michael 2017-05-28T16:51:22Z

This just happened to me in a single player world. Could not generate a crash report on the death screen, but did when I respawned. Attaching pic and report.

I went into spectator mode, down about 30 blocks (solid all the way down to a ravine). Came up, switched to Survival and died. I was at full health and dropped less than a block.

Michael 2017-06-17T16:55:36Z

I wonder if this may be related in some way to MC-14167.

wobst.michael 2018-02-18T18:14:56Z

Is this still an issue in the most recent versions (currently that is 1.12.2, or the latest 1.13 development snapshot 18w07c) of Minecraft?

lord.quadrato 2018-05-19T19:55:23Z

I cannot reproduce it in 18w20c

kumasasa 2018-05-19T20:30:25Z

Let's wait for @unknown to make his tests.

Michael 2018-05-21T04:15:11Z

Thank you. We will probably wait for the 1.13 or the pre-releases as this may require hundreds of hours of playing to trigger the bug, and I have to convince my wife not to go into creative and landing when switching from spectator.

Thommy Siverman 2019-12-03T12:57:04Z

Can't reproduce on 1.15 Pre-release 3
