No, just one - it’s just that I’d swear the one used to change in my game. I’d have the 3 locked traits that were set when they were made or aged up, then a fourth based on the current aspiration. But perhaps that was the bug and I just never realized. I only just got Sims 4 two years ago and at first was focused on careers not aspirations... so my game may just have been bugged several months in allowing it to change and I thought that was normal.
Still a bug that the remove_trait cheat removes the icon but not the effect.
And, I suppose, that in CAS after using that cheat it looks like you’re getting a new trait when you’re not... but now we’re just into ramifications of cheats so that last one wouldn’t really be an issue.
