@rayzac I made a Whippet in CAS and gave him the Smart trait and then checked him again after saving & adding him to my household. So far the Smart trait has not disappeared.
I went back into CAS and used the genetics option to give him a daughter mixed-breed Whippet and Italian Greyhound, also with the Smart trait. I checked her after adding her to my household and so far the Smart trait is not disappearing for her either.
I didn't change their appearances at all in CAS when I was creating them, other than using the randomize button a few times on the second dog. I'm trying to figure out if there is anything else I did differently. I'm checking their traits by having one of my Sims use a mirror or dresser to "Plan an Outfit" so I can see both dogs' traits in CAS. Are you using a different method?
Also, after you removed your mods did you delete your localthumbcache.package file? Maybe there is still something from a mod that has been stored in your cache that might be causing this?
Ok a little more testing - create a small breed NON-Smart dog - then go into cas fulledit and change one of the traits to Smart.Scratch this.
Yes deleting thumbcache.
Another possibility that I may have overlooked - pets created prior to the patch that did not already have the smart trait. When trying to give them the smart trait, it drops it altogether (sorry for the run around - been trying to figure where the catch is).
