I haven't poked around the files that vilia's uploaded, but as far as I know they contain my first round of betas, which were adult faces only.
Yep, first round of betas and those you have released as completed 02, 25 & 27 (with the betas for those removed). It's great you have a couple more to try out. I can deal with the teen males - everyone tends to go through a 'plain' stage at some point in their lives and it is nice to see them grow into their features when they get older.
I greatly appreciate your suggestion to not use Nailati's templates and for directing me away from them to something else but I think I will use them anyway and just muddle through with trying to figure things out on my own instead of asking for help again.
Well Nailati's will be the best set of realistic templates when they are complete but not all the sims will be conventionally 'beautiful' which may not suit all simmers.
One set of templates is all that is needed - so delete the one that is not in ...My Documents\EA Games\The Sims 2\Downloads.
Also, deleting the CASThumbnail.package is all that you should need to do. If that doesn't work, check your graphics settings and try again. If it still doesn't work then ctrl-right click on the face in CAS to get the thumbnail to regenerate.
