The addition of the new 1949 content broke the build in interesting ways, due to the presence of some anomalies such as empty num elements. After fixing the errors and adding some Schematron to avoid the problem in the future, we eventually got everything building again, and now we can see the streets files with the additional year. I had not updated the name exclusion list (names which match the Japanese name regex template but which are not Japanese) since the addition of 1943, so I went through both those years, expanding the list considerably. This is important ahead of the auto-tagging we're planning to do.
