On Fulgora, the Stone Recycling recipe appears to generate more stone than it consumes.
The recipe:
Input: 1× Stone
Output: 2-3× Stone and 0-1× Sulfur
This results in a net gain of stone, allowing infinite stone generation from a single unit. In practice, this causes factory deadlocks, as stone recycling loops continuously overproduce stone and clog logistics.
