Armor Stands are not updating their rotation when being teleported with rotation values.
1. Summon armor stand
2. Don't teleport armor stand in x y z directions: /tp @e[type=ArmorStand] ~ ~ ~ ~20 ~
3. Armor stand does not turn visually despite multiple runs of the command.
4. One way to update the rotation is by teleporting them in any x y z direction: /tp @e[type=ArmorStand] ~ ~1 ~
