[MC-77958] Pistons don't work properly

A piston powered via redstone on the top doesn't retract on certain signal strenghs when the signal is turned off.
This only happens when the pistons aren't attached to each other and the signal strength is an even number bellow 14.

Any problems with pistons are caused by Mojang deciding to make the piston a BUD instead of actually creating a block for that purpose. They have decided that it is intended behavior, so enjoy the extended pistons with no power source. That aside, this actually relates to a different issue with redstone not powering blocks when it should. I don't remember which issue it was and I don't have it written down.

This is different to BUD powering. This involves powered blocks being in DIRECT CONTACT with pistons, and still being incredibly buggy.
