I get an error on launch when this mod is used with Krastorio 2 and without SE:

Failed to load mods: Error in assignID: item-subgroup with name 'water' does not exist.

Source: water-softening (recipe).

Mods to be disabled:
• ChemistryForYou (0.5.0)

The smallest set of mods I've found to produce this error:
- base 1.1.109
- flib 0.14.2
- Krastorio2Assets 1.2.3
- Krastorio2 1.3.24
- bztin 0.1.13
- Nylon 0.5.2
- ChemistryForYou 0.5.0

Works with Space Exploration (for water subgroup) and BrimStuff (for potassium-nitrate.png) added.

Thanks for the note. (BTW, it was your earlier comment that helped me realize tin & nylon were needed--thanks for that.)

At the moment I'm not looking to go full SE, so I hope K2 will be supported on its own.

Sigh. Accidental double-post :|

Here's a patched version that works without SE and BrimStuff.
The link expires after 30 days, so hopefully the mod author will have fixed it by then.

Mod author did an update, bztin and Nylon are no longer required, and Krastorio 2 works without BrimStuff

Still doesn't work without SE so here's a new patched version

For the mod author if you're reading, the lithiumChemPrerequ on line 12 in technology.lua needs to be moved into the SE block to make it work

if mods["Krastorio2"] then
    sodaPrerequ = {"kr-fluids-chemistry"}
    alumChemPrerequ = {"kr-fluids-chemistry"}
    lithiumChemPrerequ = {"lithium-chemistry"}
    if mods["space-exploration"] then

to

if mods["Krastorio2"] then
    sodaPrerequ = {"kr-fluids-chemistry"}
    alumChemPrerequ = {"kr-fluids-chemistry"}
    if mods["space-exploration"] then
        lithiumChemPrerequ = {"lithium-chemistry"}

Thanks again.

I've been trying out the first patched version, and it seems to be functioning well (though I have no idea whether I'm getting the intended balance without SE, of course). Appreciate your detailed notes; hoping Timeken will find the dependency notes and SE-compat code helpful.

Looks like version 0.5.2 has fixed the issue. Thanks, Timeken (and Ponasho).
