Multicraft (I know): 17.06 17:07:13 [server] Server thread/ERROR [biomeidfix]: The mod biomeidfix appears to have an invalid event annotation EventHandler. This annotation can only apply to methods with recognized event arguments - it will not be called
This error occured a good deal before the server crashed.
