To Bejaymac:

Please give me an exact location to teleport to and I will check out your construction.

Regarding the change in states / colors: Do you recall what you were doing when this happened?

Did it happen while you were moving a structure?

Did it possibly happen while you crossed a zone boundary? (Zone boundaries are at 512, 512 as well as when a zone number changes)

When those two walls turned to yellow, did they stay yellow despite you continuing to move ghost projects, while other parts updated correctly?
