I am trying to download a website that has a few ten thousand of /1 - /332442
but the copier always stops at 1000 and if I try to download above 1000 in the
same project it deletes the 1-999 that I've already downloaded.  This also
happens with 1000-2000, it stops at 1999 and says that the mirroring is
complete even though it isn't.

The pages are not very large (~70 kb), so there is not an issue with space,
but I can't seem to figure out how to make it download more than 1000 pages at
a time which is very frustrating.
