I am using to redstone reader, but using 2 piston and 3 rail create makes fake diagional rail.
Step to reproduce:
- Create 2 pistons, but 1 piston facing and more piston is above and 1 under the block is facing to block
- Place redstone 2 piston and lever
- Press the lever, and try again even making fake diagonal rail
Warning: Affected in java edition.
