I found this issue during testing: as soon as I fire and the boss health bar pops up, the server kicks the player immediately, and an error appears in the backend.

Thanks for reporting this. The latest Rust update broke the boss health bar, which caused the kick. It's fixed in 1.0.3, just update the plugin and you're good to go.

Changed Status from Pending to Fixed
Changed Fixed In from Not set to 1.0.3

As expected, it's working now. Thank you so much!
