Summary:
If the generic movement speed is modified with the attribute command, it will reset to the default value again after rejoining the world.
Steps to recreate:
/data get entity @s Attributes[1] ( to see the current value )
/attribute @s minecraft:generic.movement_speed base set 2 ( Set it to 2 )
leave and rejoin the world
Now the Player has the default value again. (can be checkt with the first command again)
Only happens to the movement speed attribute.
Expected result:
The player should keep the set movement speed after rejoining.
