-
Launch the game and verify the mod appears in the Mods menu
- Most COIExtended mods can be used together
- COIExtended.Core should be loaded if you want the full overhaul experience

AvailableProductslist (deterministic per site) - Player chooses which of those products to extract via UI; buffer and output update accordingly
- When spawned, each mine rolls 1–3 possible products from its
- Some advanced materials (e.g.
Manganese flakes,Cobalt powder) are not directly mineable:- Obtained via trade or variable mines that rolled them
- Water‑in, gas + wastewater‑out wells that mirror real fracking behavior
- Tied into extended water treatment and waste/brine loops

Contains only the Smart Zipper (Smart Balancer):
- 8‑port, power‑aware splitter/merger:
- Per‑port priority levels, product filters, and throughput caps
- Per‑port "bucket" accounting to enforce soft rate limits over time
- Even distribution modes:

Tweaks integrates cleanly with both Core and mostly vanilla games.
StoragePlus replaces the vanilla storage inspector with a persistent, configurable panel.
- Per‑storage capacity
- Change capacity via text field; updates underlying buffer capacity
- If new capacity is lower than current contents, excess is pushed out through the logistics buffer (not destroyed)
- Make Default
- Writes the current capacity back to the storage prototype and to StoragePlus config
- Future storages of that type spawn with your chosen capacity
Allow Alltoggle:- For non‑nuclear storages: Allows any compatible product of the same product type
- Works with enhanced product picker for products beyond vanilla
StorableProducts

- Resource mining rates
- Settlement consumption and food consumption
- World mine reserves
- Unity production

- Useful for:
- Testing recipes and chains
- Building blueprints
- Emergency cleanup in broken saves
⚠️ Critical Warning: This is not a generic "remove any mod and keep playing" tool. It is only for cleaning dead config references from saves.
sanitize_configs
- Reflects into the game's internal dependency resolver and
GameSaverto:- Remove mod/config instances for mods that only leave configs (e.g.
COIExtended.Cheats,Tweaks,StoragePlus, etc.)
- Remove mod/config instances for mods that only leave configs (e.g.
- Produces a save that no longer hard‑references those configs
- Custom buildings, products, recipes, entities, or world changes
- If you remove a mod that added content the save still uses, the save may still crash
Always back up your saves before running sanitize_configs.
