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.
