[1.18] Sides Issue

[MonkeyKnight]

I am having an issue running a server with my mod. I know that I am reaching across sides somewhere in my Mod, but could not find where this error is occurring in my mod. The crash report that I have attached below mentioned that it involved the LocalPlayer. However, when I searched my mod for LocalPlayer, I only found one case in the event that I have attached below. Can you find where I errored?

why on earth did you check the ThreadGroup inside a client only event?

Remove it and try again
