bot.joinVoiceChannel doesn't work in dev

`bot.joinVoiceChannel(config.voicechannel_id).catch((error) => {
            bot.editMessage(config.textchannel_id, sentMessage.id, ":warning: |`ERROR`| Error joining voice channel, check console!");
            console.log("VOICE CHANNEL JOINING ERROR: " + error.message);
            return;
        }).then((connection) => {`

Doesn't seem to join the channel, works in 0.2.0 but not in dev.
