Don't you have problems with "Tweaks"->"Genetically modify Active Sim" option?
I can set everything perfect except sims's weight and muscle. I set a fatty sim to maximum fat and maximum muscle and in the game after a minute the sim looked like exactly before I changed her look.
I changed her look 4 times, she changed back in game 4 times.. This happened with other sims too.
I think that option doesn't work anymore..

That "he" is me.
I asked the question.
I have NRaas Supercomputer but I can't add/remove lifetime rewards. Is it in the newest one?

Edit: I found it. Yes, it's in the newest one. But it says: "Traits \ Clean : Wipes out all traits and lifetime rewards for the specified sim.  Use at your own risk." So that clears all the lifetime rewards and traits..

?

No. I would like to delete Lifetime reward what my sim owns. (Fast Metabolism)

Can I delete somehow a Lifetime reward?

The same happened with one of my sims.

It's a great mod but can you make a little change?
I would like to make the sims don't wash hand after using a toilet when they will have a bath or shower after toilet.
Maybe I wrote it unintelligibly.

I tried the newest one too, I could play with it for 1 hour and it managed with two saving and it crashed during the third saving.

I forgot to write that the crash was in Riverview with the new mod.

I played with the new mod and I could play with it two hours once I saved and didn't freeze. I was really happy. But after 2 hours in gameplay doing nothing specific, my sims were reading the game and the computer froze again just like before.

First this hack worked great but after a while and some downloads my computer froze all the time. In CAS, in the game, during saving.. all the time! I couldn't play more than 15 minutes. I tried everything, finally yesterday I deleted awesome mod and my computer stoped freezing. I could play for four hours when I quit.
I'll try the new one and I'll see what happens.
