I just have the quest where I have to bring a sabretooth tiger back to a palace. Of course the place is filled with sabretooth tigers, giants, and orc sergeants, which my argonian assassin has little chance against with a dagger and shoddy marksmanship. I used the quest cheat to find the tiger, got the message that it was tame, and yet it still attacks me! Worse still, it doesnt seem to follow when I do the save/load, alt f11 teleport back to the entrance, or fast travel.
I think this quest is either bugged, or just not worth it.
My memory is fuzy as I haven't got this quest in a long time. I believe you are supposed to "Use" the bell you are given when you see the tiger. He should then "follow you" (Dissapear), and then you can get back to the noble to whom it belong to. NPCs and monsters cannot follow you in real-time, instead you see their face in the left part of the screen. With the tiger, I don't remember seeing its face there.
Well,the problem must be the notice comes up and goes too quickly/ I have noticed that if you equip something enchanted the info of the enchantment immediately appears over the text along the top of your invenotry and is immpossible to read.I wonder if the disease message can appear while you have the inventory open and just appear unreadable over the top of the inventory screen?
Always check your condition when traveling through a dungeon. It's the same key as checking what time it is, which province you visit and what is your standing in that province's law.
And, yes, diseases messages always appear a few hours after you caught it. It's not a bug.
