So I found a bug a few months ago on bedrock when I was trying to create an automated Minecart system and found out that you can slope rails onto nothing with pushing.

Platform

Multiple

Operating System Version

Windows 11, Android

Affects versions

26.45 Hotfix

Description

Short description of the issue

When a sticky piston pushes up 1 rail block, the adjacent rail block will change it’s permutation from being flat to go up/down. Later, as the sticky piston returns the rail block back to its original height, the adjacent rail blocks got popped.

Steps to reproduce the issue

  1. Place down 1 sticky piston, facing upward; with 2 blocks next to it; forming a 1x3 platform

  2. Place down 3 rails (any types) on top of the 1x3 platform

  3. Power the sticky piston with a button
    NOTE: View attached video bedrock_behavior.mp4

Expected result

The adjacent rail block should change its permutation back as expected, confirm by doing the same on Java Edition (View attached video java_behavior.mp4)

Actual result

The adjacent rails got popped instead.
