This is two parts, the first I think is a glitch just asking the community if they have the same experience, and then just a side question.

Glitch?

I have two characters a warrior heavy nord, and mage heavy breton. So on the mage I have completed the colleges main tree of quests. I was running around the balcony looking for Phenis Gantor (SP?) when a dragon shows up... So I immediately go through the hall of countenance to the courtyard to fight it.

But what I noticed, that I had never noticed before when fighting a dragon was as I was in the Hall, the red "enemy" dot was still on the compass.

Now ever since then, at a very high frequency the red dot shows up in the HOC, and a dragon always shows up outside once i leave the hall... i have fought about 6 dragons at the college since the initial attack. opinions?

(digression but after I beat Alduin with the warrior class I have, I noticed a major uptick in dragons. I had never experienced two dragons at once and I cant seem to trot through the northern section of skyrim anymore without dual dragons appearing.)
