Disappearing sweaters with scarves......

Yep, I have it pretty regularly with the knitted items. I did a ton of knitting a few generations back with my founding family and it seemed completely random whether things would or wouldn't unlock like they are supposed to.

One thing to make sure to check as well though, is if the things that 'look' locked, are actually available if you click and change them to the color swatch which you actually knitted. I had that happen as well.

I love the Nifty Knitting stuff, but it is kindy glitchy (at least for me) when it comes to CAS unlocks.

Me too - it's so frustrating when you can see the clothes you've maxed out the knitting skill but all the clothes you've made are still greyed out in CAS

Yeah, it's happened to me recently, but originally it didn't.
