Hi,
In Solitude I first made a lot of quest for people in town and just afterwards the Jarl's quest. When the entry about helping the people apeared after I finiehed the Jarls quest it was directly showing (5/5). I also did the quest for the Shield of Solitude and finished it before the Jarls quest.
Now ihe Jarl made me Thane, I bought the house but the entry with (5/5) is stuck in my quests page. The quest log has the "show on map" active for that entry but there's no marker. Is this an issue or am I missing something? Could I trigered bigger issues than a simple stuck entry because of that?

PS: Another issue I notice is about the quest entry to visit your new house in Solitude. If you entry trough some other door then the marked one this misc quest gets stuck too even if i exit and entry again but the marker on the map disapears. But for this one i can reload without replay too much.
