Version: 12.0.0-beta-4

Zinc is used in the crafting of some items, but it cannot be found. How to fix it or where to find it?

Check if you have a "mine_zinc.cfg" in "/config/railcraft/ore".

Zinc was added later and the default configs are only created once, see the "generateDefaultConfigs" setting in "railcraft.cfg" if it is missing.

I tweaked the generator to pair zinc with lead mines and added a log message when a ore config is loaded.

I doubt this will actually change anything for you if zinc isn't actually generating, rather than simply being unable to find it. It also won't affect already generated ore configs.

it is generating, but at narrow height ranges.

@liach

In which biomes and at what height should I look?

@CovertJaguar

Can you please compile this version for me so that I can check it?

sorry. i am away now, and will tell you the range when i got to a computer.

UPD: I decided to install the mod "XRay" in order to check the presence of ore in my world. It turns out there is zinc, but it is just in one small area (at least I haven't found more places.) and nowhere else is it. Is this a mistake or should it be?
It seems to me that on servers of such amount of ore there is very little for the players.

It should be at exactly y=30 horizontal plane. It has a very tiny distribution range.

Mines are rare, that's how they spawn.

Also the rich biome thing is currently broken, so its the same for all biomes.

Should be fixed in 47e0953. Rich biome thing should be tracked separately.
