I searched but found very little.

Is this quest currently broken? I have exhausted everything I can think of yet still cannot enter the mine.

Am I missing something? I collected the three items but the voice behind the door will not open. The door says it's open but I cannot enter.

I have restarted the quest to no avail. Just wondering if it is a common issue with others and if there is some work around. I will restart it again and see what happens.
