Likewise I've never seen a limit. I did some ... erm... 'testing' (cheating?) back in RTW when I discovered the 'give_trait' command. I am absolutely positive that I had one guy with well over 40, if not 50 traits before I decided to give up. As such, I doubt that there's really a limit, and if there is, I doubt you'll realistically be able to hit that, unless you are trying really hard. Good luck mon ami!
