CityDamagedByPillagedTiles
This mod makes it so each pillaged tile deals damage to its city (please read the NOTE below). The default damage per tile is 5, but it’s easily changeable in the Lua file. If you’d prefer this value to be determined depending on how may tiles a city is working, consider my other version of this mod.
NOTE: The vanilla function I use to check tiles is a bit mysterious. Sometimes multiple cities are considered to be working the same tile (even if one of them is 5+ tiles away, or belongs to a different player), sometimes a tile nearby won’t count as being worked.
