The Silent Cave - Successfully completed but stated as Map Failed - Reference 2.829.666.110

Hi there

I ran the map The Silent Cave. I could not start the boss encounter. The boss essence could not be activated. So I run an other map and than started the map Silent Cave again with a new waystone. This time I could start the boss encounter and I successfully completed the map. However, now the map is shown as Map Failed even it was completed correctly the 2nd time.

Please check it.
Bug Reference 2.829.666.110

Thank you very much
Kind regards
