Build: 1.8.5 3859 Mode: Survival / Creative Mode: Single Player / Multiplayer Reproducibility: Always Severity: Minor Type: Blocks (Spotlight) Summary: Spotlight Slope's collision box does not match its geometry. This results in issues with airtightness and player / weapon collision. Description: See screenshots. Placing Spotlight Slope in its normal orientation does not result in the expected airtightness (green on left is default, green on right is upside-down). The normal (red) and Slope - Horizontal (blue) appear to work correctly. The second screenshot shows the player walking "up" the spotlight as if the slope was in the wrong direction. Steps to Reproduce: Place a Spotlight Slope in its default orientation with the back sealing an airtight area. It will not seal. Place a Spotlight Slope on the ground in multiple orientations and try to collide against it with your avatar. It will not behave as expected. The attached .epb is of the setup in the screenshot below. Screenshots:
