Expectation: Armor stand would just chill in the back.
No, I did not have a teleport command running to rotate it or anything. Yes, this world was created in the version used.
Steps to reproduce are in the video, but also below
Armor Stands only start to spin once the boat is rotated. The more the boat is rotated from the south direction, the more it spins, plus the more you wait, the faster it spins. It seems to just rapidly switch from south to its correct rotation. Something about the armor stand's direction not correctly updating according to the boat's rotation.
