Ar Tonelico Qoga : Knell of Ar Ciel [BLES01102]

Yeah looks like it broke. Keep trying a few times and if you (like me) can't get the intro to load open a bug on github with this information.

At the same time, this game was always very unstable (my theory is thread synchronization issues) and perhaps we are seeing a worsened symptom but not the cause with those mutex changes...

Tried two times: failed the first, worked the second. I don't think the game has regressed in any way, it's perhaps just randomly slightly less stable. Or not. The real bug(s) was and is still there.
