Elevator chooses the wrong controller block as the floor block after server restart.

[Kass401]

Issue Description:

After restarting a server, the elevator reads the wrong controller block as the block the floor is set on. Everything works fine when set up, but after a reset the issue happens.

What happens:

The elevator lands one block higher than it should, meaning the control block at the top is chosen as the floor block.

What you expected to happen:

The elevator should've landed properly, thus choosing the control block on the side as the floor block.

Steps to reproduce:

1. Create a Minecraft server.
2. Build an elevator
3. Build a frame with a controller block above and to the side of a frame B - any blocks C - controller blocks B C B B C B B
4. Set up the controller blocks so that the upper controller block is in floor display mode and the side controller is a call button and a floor block.
5. Restart the server
