Stuck In LImbo on Another Boss ... this time "Krux of Nothingness"

This is now the 4th boss encounter where this has happened... One the Monkey Boss would not grab the bell and becomes invulnerable and you cant leave, only way to fix was to let him kill you and lose 10% exp. Another was the Snake Lady boss that would not let you leave the arena... Now in the second phase of the King of the Mist fight, he just sits on the pathway and does nothing, and you can not port out and restarting game does not fix...

Now im just Stuck in here with no way out and can no longer play the game... How do I resolve this issue
