Did you use the graphic importer plugin in Fshed 0.0.5?

Try not to overwrite the logos from peter83's mod.

Extract the files from the original data.gob using Biggui and modify this file.

Each .fsh file has a name, metal.bin and bin attach that is unique to that file.

The game loads the textures based on their exact name within the .fsh.

If there is a mismatch, you will get either a  blank white logo or it will revert.
