Can confirm in 1.17
Did some digging on this. Turns out Striders set their NoGravity flag to true when they're in lava and to false when they aren't; that's how they float. Certain things can make the flag get stuck on true. A consistent and easy one is just saving and quitting while the Strider is standing in lava. After you reopen the world, the Strider is stuck floating at their current height forever. The flag being stuck like this also prevents them from walking up blocks, which they can normally do.
This also relates to MC-176203, as the NoGravity flag prevents levitation. Striders probably shouldn't be using that flag; it's mostly intended for command use only.
@violine1101 I actually don't think that's a duplicate. That bug is about how, when the lodestone is broken, the compass is still a Lodestone Compass, just a Lodestone Compass that points to nothing. This bug is about how, when the lodestone is broken, compasses in containers won't notice at all, and will continue to point to the lodestone's old location until they are placed back into the player's inventory.
Confirmed for both 1.15.2 and 20w07a.
I was unable to reproduce in 1.15.2. Seems to be resolved.
Confirmed for 1.14.4 and 19w41a.
I suspect that this is happening because villagers have a much smaller hitbox while sleeping.
Confirmed for 19w04b.
Confirmed for 18w32a, with the upper limit of distance= in place of r=. Setting only the lower limit has no effect, so
distance=1000000..
will not trigger the bug, but any of
distance=1000000
distance=..1000000
will.
And for 18w32a.
Confirmed for 1.13.
Confirmed for 1.12.2 and 1.13-pre5.
Confirmed for 18w16a.
Confirmed for 18w10d.
"any block with block states will always fail to match in a command argument"
Not true; that wool example will detect white wool just fine. The problem is that, instead of missing blockstates using the default value when setting and accepting any value when testing, they just always use the default value.
Confirmed for 1.12-pre5.
So does that mean that there's now a maximum chain length? If so, what is it?
@unknown Thanks for the correction.
Can confirm in 24w06a.
@@unknown Eight-year-old comment, but it seems to me that the "correct" solution would be to do attribute application in two passes. First, go over all the slots as you described, but only process item removals. Then go over all the slots a second time and process all the item additions.
