Hello :)
The "Foodtorio" by "MrEktidd" mod also has salt.
Due to duplicate salt items, the early game salt from "Foodtorio" cannot be produced.
"Foodtorio" salt is unlocked in Red Science and is crafted from a material called "Raw Salt," which is crafted from 1.0k regular water, not "Seawater."

I also reported this to "Foodtorio."
It would be nice if compatibility could be added.

I will add compatibility in the next update.

I couldn't find where foodtorio breaks, there won't be any compatibility with it yet.
