Are you doing anything weird?

Using KettingPowered on server.

On client-side works fine.

Hello, thank you for reporting this issue. After looking through the Ketting code for a bit, it looks like they're directly patching the games code in a way that is not safe for mod compatibility. Fixing this issue would likely require developing a version of the mod specifically for Ketting but my hands are already full with Forge/NeoForge/Fabric/Quilt support and all of the new updates Mojang has been releasing.

The previous version 12.0.2 may have better compatibility with Ketting but that version is missing the bugfixes from 12.0.3.
