Hi MrsFlynn
Thank you for your reply, I have tried all of what you suggested and have read the post/s you are referring to. I am using the cheat correctly because it worked this morning for me I had to go do something else and shut the game down, later around lunchtime I opened my game again and it needed an update so I did that, now the cheat doesn't work, it's quite a popular cheat too so I'm hoping that it is fixed when I purchase Day Spa on the 14th.
cheers
SOLVED
I have finally after all day trying to work out what was wrong found a fix.
I repaired the game, moved my sims from one town to another and then back to original house.
Anything other than what I just listed didn't work, believe me I tried everything.
Typed in my command testingcheats on then used my Stats.set_skill_level major_ *****cheat. YAY finally working.
Sorry to have wasted anyones time, but at least now if anyone else gets this issue they can solve it.
cheers
