MOVED: Any one having these issues with cops?

Block shape matters here, and possibly not just for the walls, but for the floor and ceiling too. I vaguely recall a content creator exploring this in depth in a video, an alpha or two ago. If you're encased by solid blocks on all six sides, then they shouldn't spit like they have line of sight.

Block shape matters for weather too, while block rotation doesn't. If your roof is made of half blocks for example, you'll get wet even if they're rotated to visually form a solid roof.
