I completed the first quest with choosing a crystal to activate (although after watching a video guide, it didn’t look like that when I activated it, with “flames” appearing), then went with a friend to do some WQs while he had time for it, then came back later to take next quest in Mardiva’s Laboratory questline where I have to activate the device. I clicked on ‘activate’ and enemy appeared, which I killed.
But I can’t complete the quest, because no matter how many times I click on ‘activate’ device it doesn’t activate it.
I have tried to reload ui several times, tried to abandon and retake quest several times.
