I'm wondering if this is intended or a bug.
When you sit in on class for a number of times (that came with DU) you get a Mixology certificate, now this is nice. What I am wondering though is; should you get in regardless of what classes you go to?
I didn't mind it before but I have now realised that it is an issue if I want to use the feature but NOT get the certificate. I can't use the function of sitting in on class then, because it doesn't have to be mixology classes (or even cooking related classes) in order for you to get the certificate.
I don't want a sim going for mischief or robotics etc classes to get the certificate (that might not make sense for that sim), especially if they already have a degree, or are working towards one.
I play on PC with no cc or mods.
