My friends, my brother and I made a server to mess around on and whenever we try and use a head or body that we put in the head and body folders on the RC the head and body both appear invisible, making our characters invisible. How do we stop this? Thanks in advanced. 
This is probably because the heads and bodies are not 8bit png or gif files. This version of graal can only handle 256 colors, so either save them as gifs or save them as 8bit pngs.
I tried this with a body, the colors are fucking bizarre now.
