dlc Elder Scrolls Hearthfire Glitch

Unfortunately i cant help, but i can point out another problem with the DLC.

During Hearthfire three plots of land are available. One you aquire from Dawnstar which i have and another two (One from Falkreath and one from Morthal) both of which i do not have.

You must talk to the relevant Jarls stewards to aquire each plot of land, (Aslfur in Morthal and Nenya in Falkreath). However when i talk to both of these characters i have no conversation option what-so-ever mentioning land or houses.

After trawling through some forums i doscovered that you may have to do a couple of randomly generated missions (killing bandits, giants etc) for the stewards before they will sell you land. Thats sounds fine, but here is my problem.

I visited these towns very early in my gameplay and added their random missions to my massive list of miscelaneous quests. I have absolutely no idea what radiant quests apply to each steward and have a list with literally dozens and dozens of missions. I am going to have to work my way through them until i just happen to get the righ mission.

Anyone got any ideas how i can work ou exactly what mission i should complete for each Steward ? Thanks.
