EPG not loading

I am trying to load in my EPG, which is this one: <?xml version="1.0" encoding="ISO-8859-1"?><!DOCTYPE tv SYSTEM "xmltv.dtd">< - Pastebin.com

But it doesn’t load at all in OSMC. I have to NextPVR addon with 6 channels and the IPTV live addon with about 100 channels (both PVR).

when I disable the IPTV addon and just have NextPVR enabled, it loads up the EPG fine, when I disable NextPVR and enable IPTV then it won’t work.

But when I remove a bunch of channels to about 10, it works again.

It works fine with Kodi on Windows, but OSMC doesn’t like EPG’s at all. I also find that after a few days of uptime the Guide section in TV is empty while the TV main page still shows the current program.

Is the EPG part broken or just very buggy?
