Note, many of the non-existing maps are like such by design. For example 
the floor2 thing in Brest is because that is simply unimplemented, and 
those exits are there as a placeholder which gives players a sensible 
message. Such placeholders are very common and aren't considered errors 
generally. The mlab thing is because much of mlab is not in CVS, for 
various reasons including that the creator of mlab uses a flat directory 
structure which people do not have the time to change.
/lake_country/pup_land/nurnberg/city is likely a typo

/dungeons/train/train-old for one should either be deleted or moved to 
unlinked, it is as I understand a sort of backup of the old training 
center lobby

That's my 2 cents on some of these cases.
