in minecraft 26.2 rev3 in singleplayer worlds
I use the command
/attribute (playername) minecraft:movement_speed base set 0.6
to increase movement speed.
when I leave the world and reload it(going to the menu and back to the world, or restarting the game) the movement_speed attribute get’s reset to it’s base value.
other attributes seem to all work well and retain their value so I suspect there is a small mistake somewhere in the saving or loading code for that specific attribute resulting in this bug.
Thank you for your report!
