If you set your humanoid to sitting while not connected to a seat, if you zoom in you are able to rotate the direction your character is facing. I for example have a slide that you sit to go down, but if you zoom in you get stuck at the bottom or get flung elsewhere.
Finally someone addresses this issue. I don’t know if it is meant to be a feature or if it’s just a bug, but either way it leads to unwanted results. On several occasions I have been flung by zooming in and moving.
While avoidable, this is very annoying. I hope is is fixed soon.
