Looks like this mod is causing lags on our server. ~4 hours after reboot, you can see this in the server logs:

The WarmRoast show the following:

refraction-1.3.4
forge-1.10.2-12.18.3.2254-universal
minecraft_server.1.10.2

Here full logs from WarmRoast
WarmRoast.zip

That's... impossible...

Closing this issue for clean up.
things have changed with the port to 1.12.2 and i wont support lower versions.
If the problem still occures do not hasitate to create a new issue!
