/sit and right clicking steps don't put you in the correct spot.

[Anna Bakker]

Using /sit or a chair (stairs) would normally put you in the center of the chair (or where you /sit) and make you ride a eye of ender (making it look like you are sitting).

But at the moment it still does this. but the eye of ender and player riding it are not even in the right block.

Sitting is nothing to do with our scripts. It's provided by craftbook.
