This still exists in the latest version of 26.1.2
I tried to search for it but nothing came up, apparently using / does not work in the search bar.
this is a critical error, first B snapshot in a LONG time
so basically, I won't have to re-do how did we get here when the update drops. seems good to know
this advancement requires having all effects on at once and normally should be reset any time a new effect is needed making one have to get all the effects again to complete the advancement. I believe others have needed to do this in the past when a new effect came into the game. I'm not entirely sure but it should have taken the advancement away forcing me to get it again but with the darkness effect. Otherwise I'm not sure.
The one on the left is the age 3, while the right one is age 2.
This is supposed to happen in cold biomes, and you not seeing the snow is also normal. The reason why its snowing on that block is because its at the level where it starts to snow, while the other areas are too low to produce snow. I know mountains and they behave like this.
I can edit this bug, since I do not remember seeing anything regarding rain in the posted bugs.
It also still affects 19w08b
Besides, I did just read that bug report, and this does seem partially related, but only partially.
The horse that vanished and re-appeared is the one in diamond horse armor, and it did not duplicate.
I am not sure, I just discovered a zombie attacking the approximate location of me on an untamed horse, I took some screenshots. I also found one of the horses that vanished, but I was unable to get on it.
This also isn't the first time a new mob is added w/o the subtitles for it. There have been others in the past.
It also affected the other 2 snapshot versions with the turtle and phantom.
However baby hoglins are not affected by this.
