Temple of Kopec, after killing the boss, Alva is not around

Hello,

I just killed Ketzuli, High Priest of the Sun, in group, later, the quest asks to talk to Alva, but no where to be found.

What should I do now? I tried joining other group, but cannot teleport to them.

I have restart the game few times but it doesn't work.

Please help.

If you hit ESC and respawn at checkpoint and then run back to boss room it might be fixed.
