If you duplicate a site where "organize" has been used to rearrange topics, the order doesn't stick when you duplicate a site.
Steps to reproduce:
- Create a couple of forums.
- Create topics 1, 3, and 2 in that order.
- Use the "organize" feature to put them in numerical order.
- Duplicate the site.
- In the duplicated site, you'll see that the order is the way you originally added the topics, not the order you organized them into.
