Here are some dragon problem that some of them are funny :

1.The corpse of recently deceased dragon almost every time when fast travel to somewhere ,travels with you ( specially ancient and elder dragons and (vujuulan?)

2..When you exite whiterun through its gate you can alway see a dragon is falling from the sky .

3.some dragons are essential meaning they can't be killed or even attacked ! ( weapons go throguh of the dragon's body as if it is part of the air )

4. if you have a follower with you and encounter a dragon ( usually blood dragon ) an other dragon apeaers and immediately dies ( confirmed with Lydia so far )
