This issue is not caused by this mod.
Seems like the cheat client does that.
It could be a compatibily issue with the slf4j simple implementation, but not sure as this mod is obfuscated.
Also the issue template is there for a reason. I need the versions you are using to help you.

I delete Impact and its working
