After updating from 1.7.0.2 to 1.9.2.1 the catalog_product_flat index is not longer shown.
The index is neither shown in Magento Backend nor if i call
php shell/indexer.php info
It is activated under System > Config > Catalog > Catalog > Shop
I can still call it directly via
php shell/indexer.php --reindex catalog_product_flat
and the database tables are filled and used.
Any idea how it comes or to fix it?
