Not really a duplicate, as in this case stripped versions of different blocks have the same color in-game.

The bug is present in 21w19a.

I can not test in 21w20a as that version crashes on my PC due to an unrelated bug.

Looks fixed to me in 18w14b. Tested MC-126419 "Phantoms fly into water and drown"; phantoms will still pursue the player into the water, but will no longer simply drown themselves. Good solution.

This is not an graphics glitch. If you stand inside such a blinking water column the oxygen bar appears and disappears.

I've added a simple setup to reproduce the effect.

Duplicates MC-126920

I have noticed, that phantoms chase the player even underwater, at least for one attack. If this works as intended, their survival instinct ought to be improved.

Suggestion for the AI:
When breath is low / the phantom is suffocating, then:

1. fly to a nearby bubble column (if present), or

2. hunt and eat a nearby pufferfish (if present) to gain 30 seconds of waterbreathing and refilled breath (nasty surprise for the player), or

3. glide towards the surface at 70° inclination. This way the phantom will soon reach the surface and has a chance to navigate overhangs.
   Once the phantom has replenished its breath it can resume chasing the player.

Option 3 ought to get the phantom unstuck in any of the scenarios described in the various related bug reports.

@ Grum
Sorry for the late reply. The language-casing seems to be a holdover from the MC 1.8 profile generation.

I was using an old profile for the snapshots when I got hit. It can be reproduced by creating a new MC 1.8 profile in the launcher.

Xavom has pinpointed the source of the trouble. I have edited my options.txt file accordingly and can switch the bug on and off by using en_US and en_us, respectively.

Thanks, Xavom

Confirmed under Windows 10 Pro, 64bit, no resource packs installed.

What I noticed in launcher_log.txt is the weird mix of slashes and backslashes in the filepaths, e.g.

[1122/174347:INFO:ClientStarter.cpp(619)] ${assets_root} == "C:/Users\REDACTED\AppData\Roaming\.minecraft/assets"

which do not match the regex reported in the error message

IllegalArgumentException: Non [a-z0-9/._-] character in path

I'm not sure, MC-115025 is really a duplicate.

In MC-114943 you put items into the grid, then select a recipe. The target item gets created and the items put into the grid are deleted.

In MC-115025 the recipe pulls the ingredients out of the inventory, then deletes the ingredient which happens to be beneath the mouse pointer and fails to craft the target item. (I have now attached a video to MC-115025)

Corrected teleport command in description.
Updated affected versions.
