When placing the teleporter pad on the floor behind me, it did not show when i placed it.. so i committed my design, and when i came out, the pad was there, and works...

(The bit of color difference you see is a piece of wall from the floor below it.
When i go back into customization mode.. I can no longer see the teleport pad.
So i decided to re-load my client to see if it fixes it, and it did not..
The teleport pad is on the 3rd Floor, if that makes any difference.
