On my current play through I'm level 44 with over 130 hours put in, beat dawnguard, the main quest and all through dawnguard and shortly before I seem to not have had to deal with the random dragon attacks. This bugs me actually cause I have deadly dragons and deadly dragons armory installed so i need the dragon loot to make my uber dragonslayer armor. Not to mention I miss the battles, deadly dragons does have a assault feature witch makes dragons attack after certain amount of time but for some reason they like to spawn in caves sometimes so I disabled that feature. Is my problem a bug or something cause like i said its been over 50 hours since I've had the random dragon attacks.
