Streamlink version

streamlink 6.7.4

Description

Recently, I've noticed constant warnings about stream discontinuities despite not seeing any actually happen.

According to the verbose log the playlists seem to keep having the X-DISCONTINUITY tag in them even though I'm not getting served some sort of mid-roll or pre-roll due to having a subscription to the channel in question. I'm still receiving the live broadcast.

There are also instances of repetitively getting this warning even after getting past the initial pre-roll in the event I don't have a subscription to a particular streamer.

I'm not sure what's going on in the Twitch side of things, is this some attempt at trying to break streamlink usage again?

The verbose log is too large for the issue report so I'm attaching it as a file:
