Error 123 when traveling to Britechester

I've been having a similar error for about an hour, I don't have CC or mods. The game is pure

I am also having this problem. Sim living in Britechester, attempted to visit the pub, next day tried to visit the commons at Foxbury.  got the same 123 error code for both. 

I've been having a similar problem. Only, I can go to residential lots. I just can't go to organization events (Debate Guild) or the graduation ceremony without getting this error. However, I was able to get the sim to go to university housing and participate in the debate showdown. It could just be common areas at Britechester.

I am also having the same problem when my household tried traveling to The Library on Britechester campus. I got an error message and then it left me in Manage World mode.

I’ve had the same issue, trying to play through university and can’t travel anywhere in Brichester without the error code popping up 

It's exactly the same for me. Can travel elsewhere but nowhere in Brichester. I have no mods, just cc.
