mermaids have no tails

Just bought this expansion a few days ago and saw my first mermaid today, actually I saw a few and none of them had a tail. They are all npcs so I am not going to try and have them all look into mirrors to color non-existent scales and nraas's mod does not permit recoloring scales. However, clicking on City Hall, nraas, options: civic center, Fix invisible sims, gives the mermaids their special outfits which can then be put on them with nraas, master controller, basic and outfit, even in the water although they do still swim funny.

I am hoping that goes away with time or I will give them a special outfit to set them apart from normal humans and forget about the tails, scales and whatever. Not sure how I would have solved this without mods and I am a bit annoyed that this is happening at all, it just goes to show how many things are glitched. I think the biggest reason is that not everyone has all the previous expansions installed. In many cases, unless you order them online, they aren't readily available any more without going on a real quest to find the missing expansions and I am just not that big a fan to do that.

The way I solved the problem is but another option, if somebody is having problems with anything mentioned before.
