Wait for Chris to export the database (usually once a week, on weekends) & for the snapshot binding build script to pick up the changes.
I normally use the installer script to manually download & install the new binding version.

In HABmin, delete the “node 2” Thing ( do NOT exclude) and rediscover / add to OH. It will return with the same Thing ID so your existing Items will not break, but it will pick up the database changes.
Be sure to wake up enough times so OH fully discovers it again, of course.
