Title says my first problem. So If someone puts song to queue, it plays only that song and then music stops completely. Second problem is that after a few songs from my playlist, spotify starts to play random songs… maybe that is related to “play similar songs” - option?
If you change song use the Spotify prog, it will not keep the songs playing songs in the playlist. It’s one of those, once your playlist is playing with Nightbot, only change songs with nightbot. Also, check and see if your songs in the playlist are even good anymore. Some vanish and that will also make your NB stop using the playlist.
Actually I got everything to work by disabling the feature that continues to play similar music.
