The "Group Administration | E-mail Templates" module has a function after each e-mail template there you can select if the changes apply to just the group, the country, or globally. When you choose to apply to country or globally, it replaces everything including the recipient lines. The changes should only be limited to the body of the e-mail. We were trying to make consistent e-mail structures across all countries, but they have to have different recipients for each office's reception. This caused a major data cleanup.
