[BUG on v68] Item Codes Shuffled on Loading Old Save File in v68

[Keshav-Madhav]

The Bug

When using the LethalLevelLoader mod (v1.3.0) with Lethal Company v68, I encountered an issue where loading an old save file causes item codes to get shuffled.

For example:
Before loading the mod: I have 10 Walkie-Talkies.
After loading the mod: The Walkie-Talkies are converted into Jetpacks.
This issue affects multiple items and appears deterministic (e.g., Walkie-Talkies always become Jetpacks), but the widespread switching of items makes manual correction extremely difficult.

### Steps to Reproduce
Start Lethal Company v68.
Use a save file created in v68 before the mod was installed.
Load the game with LethalLevelLoader enabled.
Observe that item codes are shuffled (e.g., Walkie-Talkies become Jetpacks).

Expected Behavior
Items should retain their original codes when loading an old save file.

Environment

Game Version: Lethal Company v68
Mod Version: LethalLevelLoader v1.3.0
Platform: [Windows 11]
Additional Information
This issue is likely due to changes in the game's internal item coding between v55 (the compatible version for LethalLevelLoader) and v68. If this mod depends on static mappings or identifiers for items, it might need updating to match v68's item structure.

Thank you for your work on this mod! Please let me know if further information or testing is needed to resolve this issue.
