Please remove them from 'active quests' so I don't feel bad for skipping their
levels in the future. This includes Ndoki forest quest which is obviously
undoable, and Save duzelton which is not obviously undoable - but just most
likely so.

Wouldn't hurt to remove all event-based or change them to give some other kind
of award than LQ. Of course new LQ's for those levels should replace them
There are also other LQ's which are in some way sucky due to they're only
doable in certain seasons etc. This sucks, change it!!
Hmm yeah and of course there are those once/boot shitty quests... blaaaah! Get
rid of them too, or at least put some info in quest room to show if they have
been done current boot.
