Telescope and Spyglass don't handle towers well

If you're up on top of a tower using the telescope or the spyglass, the "vision effect" is broken.

 

There are also problems with the telescope pov if you stack the telescope on top of something, you'll see the telescope in your pov when you use it.

 

I believe what you're seeing is an issue with the scope effect and the skybox. This should be a known issue. Thank you for reporting.

 

Yes, I think that's correct. The horizon line being the skybox, I assume.

The other issue (second post) is something else though. It's a pov issue with the telescope. Try stacking it on another item, your pov will pick up the exterior of the telescope.
