Thanks for reporting. This is another symptom of Rust doing multi-threading somewhere. I couldn't find any relation between hooks such as OnInventoryItemFind and the networking hooks (e.g., no shared state between them), so I'm not sure how there are thread collisions happening.

My best guess for now is that some other plugin is handling hooks that are being called off the main thread, and those other plugins are inadvertently invoking Item Retriever's hooks (perhaps via some game function that Item Retriever hooks into), ultimately resulting in hooks such as OnInventoryItemFind being called off the main thread as well.

I released v0.7.10 which should address this.
