Xesht bug

Hello,
After playing for hundreds of hours, I summoned Xesht for the first time. However, when the breach opened, no monsters appeared, and when I reached the arena, the boss was missing. The entire area was foggy, and I died. Experiencing this during my very first boss fight after hours of effort was extremely frustrating.
I strongly believe these boss fights should allow 6 portals and 6 attempts. Having just one attempt after hours of effort is truly discouraging and diminishes the enjoyment of the game.
Thank you for everything else...

Same thing happened to me, after another 10 days or so of grinding I have enough splinters for another try but I haven't seen anything about this issue being resolved in any of the notes so I could be trowing another breech stone to the wind.
