Since the latest update, I'm getting the Error Code 123:aa435624:b41848df in my game and can't travel to other locations.
Ideas
I've been having a similar issue since the update. A lot of the error codes for me, seems to come from trying to travel to and around Britechester's community lots and Foxbury University. My Sim was living in a house in Britechester and can't attend her society events or even go to Foxbury commons without the error code popping up. Very annoying. š
Possible work around. I had this same problem. What worked for me was to go to the lot in build mode and save it then bulldoze and replace with the saved lot. After I did this with the lots I couldn't travel to in Britechester it seemed to fix the problem and I as able to travel to them with no issues. I did it with Pepper's Pub, Larry's Lagoon and Laurel Library. Now I have no issues travelling there.
This also worked for me with the Bubble Tea & Thrift Shop.
