Cannot Progress story due to this Glitch

[Viridiana]

On the level 39 Story Quest "All By Ourselves", I cannot pick up the letter. It keeps saying "the missive has slipped through your hands" and then nothing happens. Same thing happens if i try to pick it up again.

Like.... I'm screwed

For some reason, when it did that to me, I was still able to turn it in. See what happens?
