My Lands: Black Gem Hunting

the link helped, wasnt aware that could happen or i wouldnt have built where i did. And yes, that person seems much, much stronger then i am =p relocation eminent.

I founded a new city on a set of empty land, only to learn that the outer ring was filled with alchemist labs, which appear to be owned by another player, and i have no ability to interact, demolish, etc them whatsoever even after i upgraded the dark citadel as far as it could go. Is this a glitch ...
