Issue description: Could not find anything similar to this, hope its not a duplicate.

When using an elevator the elevator will act properly until reaching its destination. From there, it will be stuck in some strange loop in which the platform is visibly there yet you cannot select the blocks to break it and there is a constant elevator sound loop. Also, you can walk on this ghost platform, however you are slowed down and it seems the platform registers lower than other blocks, preventing you from transiting to any other block and acts as I am flying. I do not know how to trigger it, but occasionally the game will correct itself and the platform instantly returns to its original position making you fall to your death if you have a deeper elevator shaft.

Steps to reproduce:

Build an elevator shaft with at least 2 elevator blocks. Screens for each set to the proper elevator block. Screen controller. I also have a redstone receiver, a scanner for a door and a screen to call the elevator that has not been set yet as I am trying to make this work.

use the elevator to go to another floor. From here the elevator is now stuck in the loop, (or at least for me.)

I have also managed to reproduced this problem, using the older ATM3 pack

Oddly though I'm seeing some slightly different behavior where all floors within about 30 blocks of the base elevator block work just fine, but any higher than this and I experience the loop as described by sonvar. I would also add that while stuck in this loop the screens also do not update as if the elevator never left the starting floor. Also once the lift is stuck in the loop going anywhere near the base elevator block appears to 'reset' the elevator back to a usable state again and the platform suddenly appears on another floor much closer to the bottom floor.
If I send the elevator to the floors where this loop occurs while standing off the lift next to the base elevator block, there is no problems, the lift stops at the floor as expected and the screens update. This only seems to happen once I've traveled far enough away from the base elevator block.

In my case only the bottom most elevator block has RF power and I am using the RF screens equipped with 'elevator button screen modules' that are all linked to the bottom most elevator.

Also something to note, this behavior was experienced on servers, I was not able to reproduce this issue in an SP world.

Further info,
I've managed to stop the loop from happening by chunkloading the chunk that the elevator is in.
