Hi
Really ? And there were no way to retrieve it from host provider ? Anyway sorry for that. I've heard that there were plans to make override.css file not being overwritten, but it's more of a joomla thing forcing templates to have a hard list of files used by template and all files mentioned are replaced by installator. Which means that the only way to do this is by creating a template's xml file during installation which is close to impossible while files are inside package.
