Now that 1.6 has been released are problems related to problem quests fixed or do you have to start over in order to have the quest fixed?

I'm only asking as I read with other patches the need to restart a character in order for quest bugs to be addressed. So far I've only been doing minor quests, no real progress with story, or faction quests and just have one Raident quest bug showing to get my reward from a jarl even though I've already turned it in, 1.6 didn't remove this from the list.

I've a level 35 character and if starting over again is mandatory every time a main quest gets screwed up this will be a never ending game for all the wrong reasons.

Any mods care to comment?
