Hi Chris,
this message appears if a way that is in the problem list is not
complete. It just means that splitter cannot "keep-complete"
this way
because the input is already not complete. It is hard to say if
that is important for you ;-)
Splitter writes these ways no matter how many nodes are missing
(if not all of them)
My intention with this message is: If you find that a way is
missing in the map, you should first check if splitter
complained with
such a message.
The problem is, that the complete way isn't rendered, if only one
node is missing. I don't know if it would be good, if mkgmap skip
missing nodes. It could course other problems.
