Error when trying to download from one specific channel

Edit feb 16: New downloads from joniosan are working again. Presumably something changed on Twitches end.

Original post:
For about a month now I've been unable to download most videos from a twitch channel called Joniosan

The channel has videos mostly either under 20 minutes long or videos several hours long. The under 20 minute videos usually work but for most of the long ones the download does not start and the program spits out this (or similar) URL in an "error" message box:
http://vod.edgecast.hls.twitch.tv/v1/AUTH_system/vods_15c6/joniosan_17986452768_357296214/high/index-dvr.m3u8

This message came from trying to download the (at the time of posting this) latest broadcast on joniosan channel that has an air date of 2015-12-01 and is 5 hours 40 minutes long. Changing my settings or restarting the program don't seem to do anything. Each individual video either always works or never does. I have never had this problem in the past nor does it occur on any other channel I've used TwitchDownloader for so I tried to be as specific as possible so maybe people can reproduce it.

Hello,
I have a similar problem with the Krayn_live channel. Downloading issue affects all VOD, regardless of length.
