Ghost muddites
 

I just ran through Xorbb and all the muddites are spectral/ghostly/translucent, not...muddy. Is that intentional? I've never seen that before.

Just saw a ghostly looking gargoyle in Mistmoore... cool looking, but not so classic :p

Those are the textures for the Sky Shrine mobs of similar type. I am guess when they implemented Velious that it some how changed them across all of the server vice just the Velious zones. You will also find it in The Hole and Cliff Golems in OT.
