Two plots in my town owned by jaholden both embassies reverted back exactly to what they were before i cleared them however they remained claimed embassies by the town without an owner. I recleared and resold the plots and it is not an issue however if this would happen to plots that have more value, i beleive it could cause some issues. I had @onceuponajano check and it appears that jaholden was not trolling us by placing dirt and stone.
Anyways no issue for me but figured i may aswell report this.
