I have your mod installed on a server, but there is a lot of spam chatting when killing the fire mobs. How are entities death messages disabled?
I still want to see player deaths.

You mean the blights? There was supposed to be a config for that, but it looks like it's not being loaded properly.

I do not know if they are plagues.
But every time someone kills a mob that lets loose hearts appears that in the chat, and it's annoying because there are too many mobs.
