Ok cool, now I know what you mean.
As far as the tga_file, It's not really a 'hard' error though, the string is fixed length string of 260 chars, yet null terminated as well, so if the string is shorter, the original (stock) files contain leftover bytes from previous saves. S3D handles this and simply drops the extra bytes, and with a save, it pads the string with zero's, which in hex looks a bit cleaner.
