How to reproduce:
Place an Always Active Repeating Command Block and enter the following command:
execute as @e[type=sulfur_cube] if items entity @s armor.body dirt run item replace entity @s armor.body with airSummon a Sulfur Cube and right click it with Stone
Right click the Sulfur Cube with Dirt
The command block will replace the Dirt with Air and the Sulfur Cube will re-absorb the Stone item on the ground
The Sulfur Cube will now have a Bounciness attribute value of 1.0 when it should have 0.6~ with Stone(Slow Bouncy Archetype)
You can check the Sulfur Cube’s current Bounciness value with:
/attribute @n[type=sulfur_cube] bounciness get(Tested in 26.2 Pre-Release 2 AND 26.2 Pre-Release 1 and couldn’t reproduce)
actually not really sure if this would be called a desync, didn’t know what else to name it
