Groups chemistry recipes together. With space age, 'organic chemistry' also gets grouped here.
Small changes concerning balance, gameplay, or graphics.
While the recipes to make spoilage are in the Chemistry tab, the item itself (for filtering and Factoriopedia) remain in the Intermediate Products tab.
Good catch, those should also be moved, if spoiling is the only way to get them.
Moved over in dev.
released.
... now iron and copper ore are in the chemistry tab (presumably because of the bacteria spoiling)
Fixed in dev, and I'm also seeing another thing that will need to be fixed, but not right now.
Taking that back, that is also fixed in dev now.
