Sims 4 Cas.fulleditmode cheat

I have the same issue.

I have "testingcheats on". Then I go to CAS and try to edit anything on my sim, e.g. name. If I then go to relationships tab, I see that sim's relationships are all messed up. The values in dropdown are not selectable, they don't look disabled, but when I select one of them nothing happens.

Also if I switch to another sim while in CAS, I noticed that their relationships get reset too even if there were valid before.

Please add this issue to the list of known issues! (http://answers.ea.com/t5/The-Sims-4-Bug-Reports/READ-FIRST-Compiled-list-of-Bugs/m-p/3445209#U3445209). I hope this way it will be resolved sooner!
