I have this issue too, and cannot submit a support ticket. Ifill out the form and upload files, click submit, watch the please wait circles go round a bit, then the circle disappers and nothing happens. Tried many times.
Im on pc, on hotfix version 1.06, and its the same, i approach any of the taxis for the epistrophy quest, and nothing happens, quest doesnt trigger and i cant interact with them at all, beyond attacking them which ends the quest.
If it helps, I left the delamain hq in an unorthodox way after receiving the quest (explored areas in the building before leaving), if that could have caused it.
Hope it can be fixed, want to do the quest, feel its relevant to later story
