Prestashop upgrades are often problematic. So the standard advice is to upgrade only when you really need to do so. Following every new version - as you seem to do - is certainly not recommended.
It is also standard advice to make a backup of your files and database before you do an upgrade. Do not rely on the backup that Prestashop makes when you do an upgrade. Their roll backs very often fail.
The best strategy in the present situation - if the SQL upgrade isn't enough - would probably be to use my free tool Copy_shopdata to move your data to a fresh PS installation of the same version.
