In 0.5.0.248b the RS-Latch is just rotating randomly. I starter at the same direct and placed the Latch a few times, each time the rotation was different. It is realy hard to build with it this way.

Why was the issue closed?

I figured it out. The rotation depended on the part of the block I locked at thats why it seemed so random. To avoid this maybe try to pre render the block when the player is holding the item, maybe then it is better undertsandable for new people (like me)

I'll probably make them utilize the arrow rotation, much like barrel placement already does.

Will be fixed in 0.5.0.248e.
