Unopenable Chest?

Ok while exploring in Wajjun Bazzar, I came across a chest named "Old Chest". Does anybody know what this is?I'm gunna feel really stupid if this is just some quest chest.....

the old chest is a quest item, you talk to a woman by the nahpui quarter, she says that she lost her son's teddy bear and asks you to recover it for her.

Yep i feel really stupid now......thought i discovered a chest like the nerfed frozen chests.....

I wish the spawning of this chest was constant though. Sometimes it's on the upper level near the lady. Other times it's at the very bottom level below and if you've completed the "find brother tokai" mission, it gets annoying having to kill every ahm fah just between her and the chest and then some. Not that the ahm fah are hard, they're just a rather annoying obstacle in an otherwise simple fedex quest.
