When I started the colony I got concerts rather often. Now after a few years in and several updates later I literally get none.
My three nobles practice rather often on their instruments, they give speeches so often I tend to stop them every now and then, but concerts...not a single one in years.
Are they still ingame? I really liked that feature and wonder what happened.
They are, I usually see one about once a year(Which is more often than -I- see one and I don't live on a backwards hellscape). They're an event like anything else, so randomness has a huge impact on it. That aside I don't know if the event has any prerequisites in terms of mood or anything. But rest assured it's still in there. You just have bad luck.
Thank you for the feedback. I will be patient then. :)
