During the update to version 0.3.015 and the conversion of the textures to the DDS format, a few mistakes happened with the Grendol texture; furthermore, according to iKtomi, a similar problem occured already in early times of Crystal Blue with the Carkarass: These textures lost their transparent parts.
For the Grendol, I fortunately could find an old version in TGA format, which still contained a 32 bit RGBA texture. Or was it BGRA? At least, obviously another mistake occured while converting to DDS, red and blue got swapped. You know how "mouldy blue" the Death Guardian suddenly looked...
For the Carkarass, I did not own any correct texture with transparency, so I had to add some again with a painting tool. Forgive me if it is not perfect, but at least you can see again that this creature has feathers!
You can download
the fixed textures and apply them manually into the file
arts/npcs.zip; or you can wait for the next update from the server; or someone will publish a complete npcs.zip file for you substitute. According to a recent IRC chat, ThomPhoenix also wants to add a fix for the backside attacks in it, so he may host it then.

Note to the developers:
I converted these textures currently into DXT3 format. If you can tell me a reason to do them in DXT5 instead, I will resend it. But if I remember correctly ... you probably prefer "binary alpha" for transparent textures, so it may not be much difference in the final result.
The textures were checked in viewmesh and in PlaneShift by a few testers already.
