I’m encountering an issue with BlueprintManager where several vanilla Rust items are incorrectly treated as locked blueprints.

The affected items (confirmed in-game via player reports and screenshots) are: Wood Armor Insert (wood_armor_insert),

IO Table (io.table),

Siege Tower (siegetower.item).

When players attempt to craft these items, they receive messages like "The <item> blueprint is locked", even though these are non-DLC, vanilla items that should be craftable normally.

With simple = true, the locked blueprint message appears in chat for these items.

When switching simple = false, the plugin starts throwing console errors (including InvalidOperationException: Sequence contains no elements) and auto-populates the advanced config with many items, which seems unintended.

Permissions are set correctly (including DLC permissions, case-sensitive), and this issue appears to affect newer Rust items added in recent updates, not older ones.

It looks like BlueprintManager may not fully recognize or handle some newer item definitions correctly, possibly in the tech tree or blueprint unlock checks.

Could you please confirm whether these items are currently supported, and if there is a recommended fix or update to prevent them from being falsely marked as locked?

Thank you for your time.
