You didn't use "Divine Save" when you changed Divine Intervention... I will write the SQL for ya
UPDATE spells_new SET effectid1 = 232 WHERE id = 1546;
This will change Divine intervention into a SE_DivineSave ... and not SE_DeathSave
Divine Save is the better of the two.. it CAN save you from being one shot.. where as DeathSave is currently terrible.
Thanks!
