When you did your last big change is when I think this when the problem started with Rytec's epg import (20180718-r0.0)
I managed to install it and have also tested to restart the box since it sometimes does not appear direct.
But I can see it in the list of plugins.
I have not thought much of it because it has been working fine with the channel epg scan.
Now I have an issue with the epg from the channels again so the lack of Rytec's epg import is annoying
I think I have solved the problem with channel scan but it's always a problem to find out what channel(s) are used.
