Armor stand won't rotate in player's direction

[Hakuyamu]

Hello everyone,

I have some problems while figuring out how I can set the direction an armor stand is looking.

I need this for a chairs script. It makes a player ride an invisible armor stand when rightclicking a stair. But due to the direction of the armor stand, the legs do not always look as they should. (Screenshots are attached, screenshot1 is where the direction of the armor stand is not as I want it to be, screenshot2 shows a naturally correct armor stand because its default direction when spawned matches the direction of the stairs)

Here is my code:

on rightclick on stairs:
    if {sitting.%player%} is not set:
        set {sitting.%player%} to true
        spawn armor stand at location 1.8 below and 0.1 in front of clicked block
        set {_seat} to last spawned armor stand
        add "{Invisible:1}" to nbt of {_seat}
        add "{NoGravity:1}" to nbt of {_seat}
        set {seat.back.%player%} to player's location
        make player ride {_seat}
        while player's vehicle is {_seat}:
            set yaw of player's vehicle to player's yaw
            wait 3 ticks

Hope someone can help me with this.

try using {_seat} instead of player's vehicle

EDIT:
If that doesn't work, try setting a local variable to the player's yaw then set the player's vehicle (or {_seat})'s yaw to that local variable

Doesn't work either. I even cannot set the yaw to an absolute value, the direction of the armor stand wont change at all..
