Hihi sorry, I joined the server to help the owner of a custom server I'm in, its a custom mod-pack (for context).
He recently had to reset the server because the servers panel flooded with errors about incendium, spesifically trailblazer and holy wrath. I don't know what exactly the issue is or what its asking. I am stuck playing telephone since I'm not in direct contact w the server owner, but can provide any extra info asked for 
Edit: we where initially playing without the texture pack and later added it after the error swarm, didnt fix anything but we dont really get what this error is.
