No, the only dragon mod I have is Deadly Dragons. I read that it can be a bug caused by Dragonborn and fixed by the Unofficial DB Patch which I have (latest version), but I don't think it's related. I finished DB ages ago and could still absorb souls afterwards, and this has only just started. I wondered if it was dragons I had already killed, ie from the named sites as that is normal, but these were in the wild. I'm thinking it's probably mixed up with the reason I can't start that other quest. Scripts or data leftover in saves or something. We can't do the "clean save" thing like Oblivion anymore to clean unused data out of saves. According to Arthmoor it doesn't work, even though some think it does.Sorry to hear that about the Dragon Souls, are you maybe using similar mods like Dragon Soul Absorb More Glorious? I hat to remove that one because i also could not absorb the Dragon Souls, but once removed i could?
It doesn't really matter that much as I'm getting the itch to start a warrior which I may be forced to do if anything else bugs out.
