hmmm....
Maybe try extracting portraits.2da to your override folder - perhaps this will help (or if there is one already - remove it). I haven't played with 1.70 patch much, I can't tell how it behaves with Java CC.
I found a folder called 2dasource.zip in the main nwn directory, is that suppose to be there or maybe it failed to unpack during installation? It has portraits.2da in it
I've tried it without the 1.7, still does the same thing.
Maybe this has something to do with it
After using the Diamond installer, when I use the .exe installer for JavaCC, it gives the error that I don't have the expansions when I do
EDIT:
Placing the .2da file from the .zip into the override folder fixed it.
However, I'm still curious about my previous questions regarding 2dasource.zip
