It's ok. The only strange thing was that you didn't see upgrade_2.3.04_2.3.05 in admin panel. Probably the file was not uploaded. Check the updates folder. You should find the sql files. I can't tell you exactly why. I can tell you only that standard 2.3.05 version creates 34 default tables. Anyway if some of the tables is lost you will see a database error. Probably, you are talking about CSV importer?
