Just a note in case this happens to someone else. When I upgraded from 2.4 to 2.5 (Moodle and the various plugins) my backups for certain classrooms started having trouble. I narrowed it down to the Collapsed Topics course format (release 2.5.3) to a message that said the table "format_topcoll_settings" did not exist. I thought perhaps it was just something that didn't go right when I ran the update for Collapsed Topics, but even uninstalling and re-installing didn't work to fix it so I had to create the table.
Just wanted to drop a note in case anyone else had the same problem.
