Issue
Dialing a Teleporter, going through the other side, then dialing the original one and going back to it will remove the Dial and everytime someone wants to go through, the Teleporter will have to be re-dialed each single time; both teleporters are Chunkloaded through FTBUtil

I'm afraid I can't reproduce this, so I can't do much.

Thank you for the report, I will investigate the issue.
