This mod does exactly what it says: Preserves your vanilla and modded features/deposits post-Ecumenopolis conversion and terraforming.

---

- Terraforming into Machine Worlds, Hive Worlds, and Nano Worlds no longer removes rare deposits and features!



- Converting or restoring an Ecumenopolis will also no longer remove rare deposits and features!
- Note: Some deposits (e.g., those spawned on Earth) may not survive transformation. A fix is in the works.

---

This mod overrides the following vanilla files:
- `action.68` (Terraforming)
- `02_special_decisions` (Arcology Project / Restore Relic World)

⚠️ Any mod that also changes these files will be incompatible.
(A patch may be required—either from me or others.)

---

This mod is compatible with:
- Ascension Planets Construction Situations (APCS) (Previously ECS)
- Guilli's Planetary Modifiers And Features
- Planetary Wonders
- Relic World Flavour
- Planet Diversity: More Arcologies
- Sparbles Hyperconstructs
- Planetary Mega engineering
- NGS

---

This mod must be placed under any mod that will effect the files edited, placing low in the order is highly recommended.
Due to APCS in-built compatibility with this mod, load that mod UNDERNEATH Feature Preserver.
Place Feature Upgrader underneath

---

- Aquisition Of Technology Habitats wipe features - due to how AOT Habitat functions, building the next tier of habitats will make the features disappear. - This will NOT be fixed.

- Earth features are wiped

---

This mod is now generally in a stable state, and im comfortable with where it is. I will continue to maintain as much as a i can.

If you notice missing features or deposits,suggest improvements, or you want to make your mod compatible, please ask!

Thanks for checking out the mod!
