@莫名某某 Unfortunately no. Basically, when calculating total for "until you have", the game looks at the id of your Productions entry and assumes it to be equal to the name of the output item to be counted. The production id "coal" is already taken for the standard coal production, and we cannot edit that to add this functionality.

Can the problem of "Until you have" counter errors be avoided by adding a product that is similar to coal as an attribute? Of course, this might require a significant amount of work. Just a suggestion.

No problem, thanks for trying.

@Phant0m5 Unfortunately there is not a solution currently for that bug. I've added an explanation under "Known Issues" within the description above. Sorry about that - I'll keep an eye out for game improvements that might change this in the future.

Thanks @Phant0m5 for reporting this bug. Can confirm the same. Will look into fixing this weekend.

So I added this to an ongoing game and the "until you have" crafting option doesn't seem to be tracking the amount of coal I have. It is correctly making coal, but is showing 0/40 in the crafting screen and thus making coal endlessly. Meanwhile the vanilla coal recipe is showing 184/30, which is correct.

I love this idea. In Japan they have a type of charcoal called Binchotan. It's pretty expensive and made out of limbs about 3 inches or so thick so this fits perfectly. And medieval charcoal makers wouldn't have thrown away sticks, they would have gone into the kiln as well.

Great mod! As this is how historically they started making charcoal that fueled early ironworks.
The conversion rate for dry wood to coal is roughly 3:1, given the amount of sticks i'd say its pretty balanced ingame aswell.

mod名称：柴烧煤

可以用木棍制造煤。

你有没有想过你可以用这些棍子做点什么？

它们太重了，不能交易。

你的木匠最好把时间花在弓上，而不是练习打靶。

但是我们有太多的垃圾了，特别是如果我们需要燃烧成吨的木头来煤制灰，从我们的动物产生的大量粪便中制造硝石。

那么，不断增长的定居点该怎么做呢？让它们在阳光下腐烂？

不!我们用它们来做木炭吧！

新的煤炭配方完全相同，只是输入的是60根木棍而不是30根木头。

我从它们的燃料比（相反的）中得出了2比1的转化率，而且它们的燃料比都是200，所以对我来说，两倍的燃料棒体积听起来大致是正确的。如果你能指出一些事实，请在下面告诉我，我会改正的。
