If this is the case you absolutely need to move right next to the tile ... you should get relocations by buying the "retreat, huge coffers" ... you get a 3 day peace treaty and a relocation (plus two other useless things) for 4100 gold ... it is the cheapest way to stay shielded and you also get the relocation ... 2 relocations a week adds up ... and they are very useful after fury wins.Thanks for the support.
Right now the new one, that just spawned and harvested once from. it takes me longer to get there and back than I spend on the tile, is now occupied by one of these bully boys, he is on about 7 others besides, and his team mates on about another 5.
Of course I have no proof , just a feeling that these tiles wouldn't even be here if not for me.
I am near the edge of the map, and had scout around, not big enough to use the watchtower, and I can find nothing else round about.
