What I'm actually writing about is this: can you tell me if there are any other mods like this? Mods that change other in-game images to be less blurry without adding anything extra, just like your mod – by simply modifying the .hdb files of the icons and nothing else. No edits, no fixes, no "it looks better this way so I decided to add it," absolutely no improvisation. Just modify the .hdb files as you did.

Oh god, I incorrectly assembled the files in the H5A1 folder. The Fixs_3.1 and Creatures&Heroes_portraits_x128 mods have been fixed and reuploaded.
