I tried it, entered cafe several times, but no error happen to me. So it is hard to say what the problem is. It is most definitely caused by loading saves from previous version. That is always a problem, as now, there are other characters and locations that were not present in the save file and that can case strange miss-matches, loops and other weird stuff. That is why it is always a good idea to start a new game with each version, but I understand, people don't want to do that most of the times.
