When trying to replace the shp icon of a unit, there seems to be somehting wrong. I followed the tutorial on this site, and everything is great. Then I use TibEd to replace the icon; yet the new icon is not in the list. When I type it in manually, its not there either.

The icon is of proper dimensions, filesize and pallet. And the XCC mixers say everything went smoothly. And the icon DOES show up in the list in the XCC Mixer/editor. So I know its there! Any ideas?
