A number of the Helltide Chests are grayed out when entering Helltide and unusable.
1600November28 - Kehjistan Helltide - chests usable.
1700November28 - Kehjistan Helltide (again) - @half of all chests grayed out and unusable in all three subregions.
1600November28 - Nahantu Helltide (Seven Stones subregion) - Several of the chests were grayed out and unusable.
I logged out and back in to check if it would reset with no change evident.
Same issue encountered on 29 November.
0600 November 30 - Kehjistan - all chests usable.
0700 November 30 - Kehjistan - In the middle zone 4 of the 7 chests were NOT usable. I didn’t bother to go into the other two zones.
Helltides are not worth doing with this bug present.
December 2nd - Helltide repeated in Scosglen. At 1800 and 1900. During the 1900 Helltide 6 of the 10 chests were unusable in the Northern zone during the repeated event (1900) and 4 of the 8 chests in the southern zone were not usable.
