Feature Preserver 3.1

🔧 Feature Preserver v3. 1 Rare features with interesting bonuses shouldn't vanish just because you paved over the planet. A lightweight utility that stops terraforming and Arcology conversion from deleting rare deposits and planetary features - vanilla and modded. -Works with most mods automatically, no patches needed -Set and forget What it does Rare deposits and features now survive: 🌍 Terraforming into Machine Worlds 🐛 Terraforming into Hive Worlds 🦠 Terraforming into Nanite Worlds 🏙️ Ecumenopolis conversion — including Relic World restoration How it works Deposits are flagged so planetary transformations don't wipe them Anything in the rare deposit category is preserved automatically Each world type has its own curated blocklist, so only features that actually make sense carry over - a crystal glacier won't survive on an Ecumenopolis, and a Tree of Life won't grow on a Machine World Unfitting deposits are removed on conversion even if another mod flagged them (Goodbye, harvester fields.) Note: some Earth-style city deposits are intentionally kept for flavour. These may be refined in future updates. ✅ Compatibility Built for maximum compatibility, no compatibility patches required. Any mod whose deposits use the standard rare category (deposit_cat_rare) is covered automatically - that's nearly all of them Verified working with Guilli's Planet Modifiers and Planetary Mega Engineering Rare edge cases may slip through (e.g. a food deposit surviving on an Ecumenopolis) - report them and I'll sort them I can't audit every mod by hand - if something should (or shouldn't) survive a conversion, tell me and I'll consider it. 🔃 Load Order Anywhere in your load order 💬 Feedback & Requests Missing features or deposits, compatibility issues, or mods you'd like covered?
