throw error irc.js

[TripleZer000]

My bot keeps crashing every week or two due to the error. I love node-irc but i am not happy with the error. I did some browsing and this what they claim to help. I do not host my code. The irc server owner does and suggested i send this.
THE ERROR
.../node_modules/irc/lib/irc.js:849
throw err;

TypeError: Cannot read property 'filter' of undefined

THE FIX!!
line 319 chanModes(mode, [modeArg]);

[modeArg] needs to be modeArg
no [ ]
