PackRat Backpack Fix Unofficial

PackRat Backpack Fix (Unofficial)

An unofficial compatibility build of SirTidez's PackRat 2.1.0 for Schedule I 0.4.7f12, IL2CPP. This is a modified full PackRat build, not a standalone backpack mod or an add-on to install alongside PackRat.

Original mod and assets by SirTidez: | Source.

Compatibility and testing

Tested locally with Schedule I 0.4.7f12 (IL2CPP) and MelonLoader 0.7.3. Save loading and opening backpacks with B were confirmed. Backpack tiers with 8, 16 and 24 slots were observed working.

Save/reload persistence, handover transactions, multiplayer and other game versions have not been verified. No Mono DLL is included; this package is not for the Alternate/Mono game branch. Treat this as an experimental compatibility build.

What changed

• Updated game API references and Harmony targets used by the 2.1.0 build.
• Replaced the missing HandoverScreen.Update patch with an update callback.
• Delayed that callback until the game initializes the handover screen, and cleared the cached reference when a scene unloads.
• Updated player inventory/load integration for the current game API.

The startup guard resolved a loading hang during local testing. This does not establish that every loading issue has the same cause.

Installation Mod Manager

• Close the game and back up your saves and PackRat configuration.
• Use an IL2CPP Schedule I profile with MelonLoader. The test environment used MelonLoader 0.7.3.
• Disable the original SirTidez-PackRat package and any other full PackRat copy before enabling this package. Keep only one PackRat DLL enabled.
• Install this package (or use Settings > Import local mod for the ZIP).
• Launch Modded. Select a backpack item in the hotbar and press B to apply/open it; B toggles an unlocked backpack.

This package intentionally does not depend on SirTidez-PackRat because it already contains the full modified DLL. The DLL retains its original PackRat identity and may report version 2.1.0 in MelonLoader; 1.0.0 is this unofficial package's release number.

Manual installation

Install MelonLoader for the IL2CPP game branch. With the game closed, replace the existing PackRat-IL2CPP.dll in your Mods folder with the one in this ZIP. Do not leave a second PackRat DLL enabled.
