Since downloading the EBN pack university features buggy.

I do own pretty much every download so not sure if it truly is because of EBN but university textbook is invisible and disappears, project/presentation board disapears and when it is available it says "does not belong to sim" even though my sim is the only one on lot and the only one attending Uni. Also homework will have a full completion circle in corner but yet sim still just sits there doing nothing as if she is still working and the university tab says "just started" when she's been working on an invisible textbook for 4+ sim hours. sim resets have been tried multiple times.
