There is a bug  that appeared when I attempted to enter through the sewer entrance to get into the cellar in the Black Iron Castle and this pops up: 

Unable to find file:

Graphics/Tilesets/B-E_HF1R_Interiors_3

There is another that pops up with this error: 

Unable to find file:

Graphics/Characters/$character05

I found this when I looked through the Tileset folder to see if maybe they just needed to be renamed but couldn't find anything really similar to the file name in the error. I ended up just picking the closest one to the error (It isn't the correct tileset) and when I tried to go in that error popped up.

The part where you go to enter Blackcry after you save Hana, I walk down the path and I walk to the part that should lead me to the next map but I just can't get through.
