Why can't I buy that tile???

Spoiler :

Firaxite tile, 3 hexes east of the city tile. I do not comprehend.

The fungus tile also appears to not be granting vision to the city. Could it belong to the city further north?

Huh...that is odd. Maybe the canyons are doing something buggy.

The Civ5 engine has had some odd pathing / ranged attack algorithms when going down 1 and then over 1 (or over 1 and then down 1). I'd bet this is the same thing.

After encountering similar problems I'd say it's gotta do something with vision. Of course YOU can see that tile, but maybe your city still can't, for whatever reason. Try buying on of the adjacent canyon tiles first and see if it helps.

This occasionally happens to me as well. I'm pretty sure it's a bug, not an intentional game mechanic preventing this.

Skip down to the "Northwest and Southeast" to see an actual graphic of this situation.

We can see in your screenshot Lucius that the tile 2 to the west of the city is not yet owned. So, BE thinks that you can't buy the tile to the Southwest of that tile.

That's my theory anyway

The city further north acquired the fungus tile. Because Pembela didn't acquire the tile, it can't buy any tiles adjacent to that tile. That would explain why the canyon tiles are also off limits and why the city doesn't have vision of tiles adjacent to the fungus.

Mhh... are you sure cities can do that? I thought that border-expansion follows the same rules as tile purchasing. If the tiles between were owned by the central city, that tile should not be available for border growth.

But assuming that cities really CAN expand to tiles that are not allowed to be bought, that explaination makes a lot of sense, also it seems kind of odd that a city would grow into a fourth-ring-non-strat-resource-tile that early. Not sure if there's a way to see which city owns the tile ingame, but selling off the northern city to another civ should give clarity about that - the tile should then become part of Pembela (because it loses connection to the borders of that northern city) and the tiles should be buyable.

It doesn't, I have many times seen culture border islands in the sea of a neighboring civ's territory. There are many forested hills around the northern city, and I have seen cities bee-line into 4th ring when special tiles are involved, as long as the tiles along the way are flat and green.

Assuming this is the same as in civ5, the owner of a tile is the city closest, or oldest in the event of a draw. When a new city is founded, it takes ownership of closer tiles, but what if the northern city grabbed the fungus after Pembela was founded? The situation reminds me of the failure to check for existing improved deposits of xenomass upon discovering [xenowell tech name], so I feel I have some basis for jumping to this conclusion.

I'll comb through the saves to see if that is the case, it's certainly possible because everything north is tundra hills so the city definitely prefered culturing southward. As for selling the northern city, that's Freeland so not an option.
