Re: Only 2 cc's show up in game each time?
@Heath23244 Just checking, but are you unzipping the files before placing them in Packages? And you're only adding .package files to the Mods setup?
The other thing to be aware of is that you can only have one "default replacement" cc item per category. You can have as many non-default replacements as you want, but only one file can be the game's default choice at a time. So the two items that show at a time may correspond to the two categories of items you've downloaded, or maybe one male and one female version in the same category. Most cc creators offer both default and non-default versions of their cc.
If this isn't what's happening, you could try pulling your entire TS3 game folder out of Documents and starting over. There's always a chance that something in this folder is corrupt or otherwise behaving badly. If you have saves you'd like to preserve, you can move them from your old TS3 folder to the new one once you've sorted out your cc issues.
