This mod allows you to create custom contracts with highly customizable parameters.
⚠️ Disclaimer: Use at your own risk.
• This mod interacts with save-critical data (contracts), and incorrect deletion or modification can break saves.
• I am not responsible for lost or corrupted saves.
• Always keep a backup of your saves if you plan to experiment.
=======================
📦 Adds a button inside the Contracts menu that lets you create your own custom world contracts.
=======================
⚙️ Customizable Parameters:
• 📥 Input & output products.
• 🔢 Quantities.
• 🏛️ Unity cost (monthly + scaling).
• ⭐ Required settlement reputation level.
➕ Click "+", set values, press Save, then reload your save after that the contract will appear in-game
=======================
⚠️ IMPORTANT – READ THIS
Contracts cannot be totally removed from saves because of serialization issues, only hidden (maybe possible but currently beyond my abilities), Therefore:
• 🗑️ Delete → moves contract to a backup file, it will not be loaded again until you restore it (it is hidden from the game contract list but not deleted)
• ✅ If your save still uses it → It will load normally, provided you do not delete or modify OnDemandContracts_deleted_backup.json
=======================
✅ Enable vs ❌ Delete
• ✅ Enabled toggle → hides the contract from the in-game list without removing it from the main contract list.
• ❌ Delete → hides the contract from the in-game list while also removing it from the main contract list. Moves the contract to the backup file OnDemandContracts_deleted_backup.json.
=======================
🚫 DO NOT EDIT OR REMOVE JSON FILES
• ❌ Deleting JSON = broken save.
• ❌ Manually editing JSON = broken save.
=======================

Contract Removal now possible.
May 06, 2026 v0.2.3- With the latest version (v0.2.3) it is possible to remove (hide) the contracts from the contracts menu in game, simply delete or disable any contract and reload the save.
- Minor UI improvement: mod window no longer blocks input in other windows.
=======================
======================= On-Demand Contracts Changelog ======================= v0.2.3: • Improved save compatibility for custom contracts. • Deleted contracts are now handled more safely and should no longer break saves in most cases. • Added automatic fallback recovery for missing contract prototypes. • Improved compatibility with older saves using deleted contracts. ======================= [UI Changes] • Removed dark background tint when opening the mod window. • The game can now be interacted with while the mod window is open. • Fixed issue where the mod window stopped working after reloading a save without restarting the game. ======================= [Important] • Do not manually delete the backup JSON files if older saves may still use those contracts. • Existing saves created with older versions should continue working normally. =======================
