What it does

bobores 2.1.2 removed the mineable sulfur ore entirely. Bob aligned with Space Age, where sulfur is a chemical product (water + petroleum-gas → sulfur) rather than something you mine — so the ore prototype is gone and the migration wiped every sulfur patch off existing maps.

This mod brings the ore back:

• Re-adds the bob-sulfur resource with the authentic pre-2.1.2 values (yellow tint, mines straight to vanilla sulfur, base_density = 8, no starting-area placement).
• Wires it into Nauvis map generation, so it shows up under Resources in the map-gen GUI (and in resource-frequency mods) and actually spawns on new chunks.
• Back-fills your existing save. A one-time on_init script regenerates the ore over every already-generated Nauvis chunk, so sulfur appears on the map you have already explored — not only on new territory.

Safe by design

• Adds exactly two prototypes: the bob-sulfur resource and its autoplace control.
• The back-fill is scoped to "bob-sulfur" only — no other ore is moved, re-rolled, or deleted.
• Wired to on_init only, so it runs once and never re-rolls your sulfur on later mod updates.

Notes

• Sulfur spawns away from spawn (has_starting_area_placement = false).
• Only sulfur was fully removed by bobores; tungsten still exists — bob just stopped placing it on Nauvis because vanilla Space Age puts it on Vulcanus, so it doesn't need restoring.
• The ore graphic is drawn from boblibrary (a dependency), tinted like the original. Nothing of Bob's is redistributed.
