Hello

After making some tests on a creative world, i have found that if you place a valid rail line over a slime block with a sticky piston under it, when the piston is powered, the two rails either side will be destroyed rather than break off the block.

This also causes abit of an update slant issue with the rails either side of the block. This happened with any rail-block

1. Piston lowered

2. Piston raised

 

Im not sure if this is intended behavior.

Hopefuly rather than breaking, the two rails either side should be flattened like:

Cheers
