Fixed a spurious "Checksum mismatch" error when editing the same premise's title a second time. Editing a populated premise's title twice in a row could fail the second edit with a "checksum mismatch" (409) error even though nothing about the premise's logic had changed. The underlying inconsistency in how the premise's stored checksum was computed has been corrected, so repeated title edits now save reliably.
