What's new

📌 Version 1.9.0

🎯 Curios API compatibility for the sandbox inventory swap

✨ New Features

  • 🧿 Added optional compatibility with Curios API
  • 🔄 Curio slots (rings, trinkets, and other accessory items) are now swapped between Survival and the Build Sandbox, just like the main inventory
  • 💾 Curio inventories are saved separately per dimension and persist across relogs and world restarts

🎮 Gameplay

  • If Curios API is installed:

    • Entering the sandbox stores your Survival curios and loads your Sandbox curios (empty on first entry)
    • Exiting the sandbox restores your Survival curios and stores your Sandbox curios
  • If Curios API is not installed, the mod works exactly as before — this integration is fully optional

🛠️ Technical Changes

  • Added a safe Curios compatibility layer that only activates when Curios API is detected, so the mod runs fine with or without it
  • Curio data is stored using Curios' own inventory serialization, so items with internal data (backpacks, storage items, etc.) keep their contents intact through the swap

🚧 Still actively working on the remaining known bugs — more fixes coming in the next update.
