Can confirm in 26.1-pre-2.
Can reproduce. Now the head of baby cats are bigger than adult cats again.
Seems not fixed in 25w02a. EndPodiumFeature.java didn't receive changes like it was for EndPlatformFeature.java for MC-902 (namely, calling destroyBlock before setBlock). Also confirmed to be not fixed in game.
I also think this is fixed. Sounds.json now properly contains a definition of the sound event.
An inspection of 24w44a sounds.json indicates that subtitle key subtitles.block.generic.fall has been added to fall sound events, though I didn't check if every event got that. This key is also present in localization files. Therefore, I suspect that this is probably fixed in 24w44a, though it's best to check that in game.
This appears to be fixed now, i.e. hn_no.json correctly appears is index 17. I remember that it was fixed in pre-1, presumably when new translation files for the Winter Drop strings are pushed, but it may be too late to check that precisely now.
Seems to persist in 24w34a with a slightly different setup, which is displayed in the gif below.
P.S. Seems to only work with minecartMaxSpeed 8 and not 1000.
Confirmed for 24w33a. Tested with corridor/end_2 sturcture.
1.21 yields seed 0 for input 0, not 48. Might need to update the description (and perhaps status); didn't test when the change happened since the duration is long.
1.21 yields the following results for the listed structures:
the 2 corridor addons minecraft:trial_chambers/corridor/addon/wall and minecraft:trial_chambers/corridor/addon/reward_upper persist to exist and be unused.
the chamber addons have experienced great changes per the existing structure files:
most of the structures are not found by their names in 1.21, perhaps having been removed, merged, moved, etc.. Further investigation is perhaps needed.
minecraft:trial_chambers/chamber/addon/walkway_with_bridge_1 persists to exist and be unused, and a SAVE state strutcture block can be found in it.
Might need to update the bug report.
Confirmed for 1.21.
Can confirm in 26.1 release that the head is tilted when and after the rabbit is walking. Also can confirm that the head is in the upright position and not the tilted position after idle animation and before walking animation.
