How can I get the Key of a locked door in the Sewer if I missed picking up after quest???

[Hershey]

I saw the article that the key will be spawned inside a bag after the quest "Inspect the Village", however I missed it due to enabled X'mas event and couldn't see the bag.
Now I can't find the bag anyplace at the swamp and can't find it from any seller at base.

Does anyone know if there is a way to obtain the key again?

There is. If you go into the CTRL+F5 menu of Debug Mode, the key to the locked door in the sewer will be under the book tab.

Thanks body. I wish I could solve this without using debug mode as it isn't comfortable to see.
