Hello,

I tried to sign up my Sim to some skill classes and noticed that despite not having the pack for it (Nifty Knitting Stuff Pack) my sim was able to take knitting classes, and gain skill points for the skill despite being unable to do anything with it.

It in itself isn't distrupting to my gameplay but I thought I should report the issue regardless. 

I have previously once reported a similar issue happening through the Paranormal pack happening and assume that it's a similar issue.

Hope I was able to help!

I also have Knitting as a class option (both in uni and as a sit-in skill class) even though I don't have the knitting pack.

My problem I think it was from a cheat or MC command center. I got all the skills including knitting and whoo hoo skills. the only stuff that I have is my first pets and romantic garden stuff.

Please fix. I own the knitting pack but ive seen so many YouTubers without the pack showing off this issue. 

Edit - Added a me too because I can see this issue when I disable the knitting pack and try to enrol into university classes.
