Help needed to access the ancient library in Egypt please

Yah, I had this issue too. Couldn't visit the household. I was about ready to pull my hair out when I finnaly thought of how to get in. But I wouldnt try this unless it's as a last resort. I went to edit town and evicted everyone in the household. Then I made it a community lot and resumed game. I lost all the sims in that household, but luckaly other sims insently took over their market jobs. So yah, then I was able to get to the library, and it was all good =)
