I'm having the same issue.
I've recently started a new save (no mods) with a sim attending university while living in brindleton bay. He has been hanging out a lot at the Laurel Library at different times of the day and there are never any sims on the lot, except for the librarian. At one time it seemed like there was a Brainics meeting on a monday at 1 AM (there were a couple of sims in the library and they had the "Brainiacs member" above their name) - which is not the time the 'Study session' activity is supposed to take place. But other than that the lot itself has been completely abandoned (there are sims walking around etc in the neighborhood).
I only started this save recently, so I'm not sure when this issue exactly started, but I do remember playing a different save and the Bot Savants meetings (the Bot building meet ups) not working / not taking place at Larry's Lagoon.
