This wasn't an upgrade, though, this was a straight import of the templates table from my back-up into my current DB.

I hadn't added any new hacks since the database was backed up last week, so all templates added by hacks are still in the templates table.

What I meant, was, that after I imported the backed-up templates table, templates started disappearing after that. As I was going through the templates, I noticed some of the Warning Systems hack and Store hack templates were missing, even though they were there when I imported the backed-up templates table!

Also, what about any existing templates that I've modified not being displayed?

As I mentioned before, any new templates that I've added aren't being displayed either, unless I set their templatesetid to -1, the master set. If I do that, then the new templates are displayed.
