How Do I Get A New Invitation Letter In "the Feathers Fly Part Ii", I Lost It.

How do i get a new invitation letter in "The Feathers Fly Part II", I took it from the chest in the armour merchant shop, then i lost it. now when i interact with the chest it says that its empty and i already found it. the shady merchant guy doesnt want to talk to me, so now im stuck on this quest.

 

try /fixquests, if that doesn't work check all previous locations of ava or any other npcs

 

i checked theres nothing

 

Had the same thing, I did this with a friend of mine and I thought I didn't need the second key behind the inn, its called an odd key or something.
If you go get that you should be able to open the crate, good luck with it
