The CEP, has maxed out the Armor, Shield, and Robe appearances allowed, (255) some are doubles to be sure, some are bugged, and then on top of that NWN has a few issues to, when the 255 limit is reached. Some times it hangs up when you scroll through them during crafting, and some times, not all the textures load up properly, when you log in. Your CEP is not bugged, just how you see it is. As for the Heads, there are a ton in CEP, and there are others that some people may have added for another Server, in their override folder. If you do not have these in your folder, you will not see them.
If you ran the updater, you will need to re download the CEP2.4a as the updater will break the latest CEP version that PotM uses
