No parent channel

[wvffle]

After testing a basic example I've faced this stack:

/root/mumble-bot/node_modules/noodle.js/src/structures/Channel.js:38
                this.parent.children.set(this.id, this)
                           ^

TypeError: Cannot read property 'children' of undefined

I've logged all the data objects in Channel.setup and the last one is the one that crashed

There is no channel with id 12 so there's no parent for channel 15. Also channel 12 is a child of 0

[Gielert]

Like you said. Channel with id 12 doesn't exist (it's not being reported by the server). Could you try to comment out line 37 & 38 in Channel.js and continue to log the data objects. It seems like there maybe some issue where your server is reporting channel 15 before channel 12 has been reported and added to the channels object in the client.
