I am looking at my list of journals and I do not see "Bloodstained letter". It is not under Beastiary, People, World or Quests. I do not think I have ever picked it up given how conscious I was with journals after mid act 1.
My guess is this bug relates to account creation as well since the date is the same as it was when the game was launched in which this item had issues based on what I read. Of course the actual reason could be unrelated.
