What this means for your game
Put the mine on the deposit first and the furnaces second, or the 1:2 ratio is only a drawing. Iron in Anno 117 is the ore chain, and the German search is Eisen. The ratio in the notes is one iron mine to two furnaces. Mines sit on deposits. When the deposit is empty the furnace does not invent ore. Weapons and tools downstream of the furnace stop with it. This is not the obsidian rule: a volcano refill was described for obsidian and for Latium deposits in the ash blogs, and I am not copying that sentence onto iron unless the same paragraph names iron. Trade from another island is the ordinary fix when fertility or the deposit is missing.
No patch line in the entity notes names a direct change to this entry.
