ZFS error message questions

After running 11.1-STABLE with root on ZFS for a week and a half or so,
I apparently screwed something up such that the system became unusable while
trying to enter multi-user mode. It looked like the easiest way to correct
the mess would be to wipe it out and re-install.
However, I wanted to save the home directory tree because there had been
important changes in it since it had been imported from the 10.3-STABLE system
with root, /usr/home, and so on on UFS2, so I ran
zfs send -ReL -I @15dec2017.freshlyinstalled-11.1S-r236620 zrootx/usr/home at 28dec2017 > /mnt/bootdisks/usrhome.28dec2017.zfs-send
which is supposed, as I understand it, to have saved a full replication stream,
including four snapshots. Now I wish to receive this into the newly
re-installed system, but here is what happens.
Script started on Sun Jan 7 00:54:39 2018
# zfs recv -dv zrootx </mnt/bootdisks/usrhome.28dec2017.zfs-send
receiving incremental stream of zrootx/usr/home at 16dec2017.post-import-from-10.3S into zrootx/usr/home at 16dec2017.post-import-from-10.3S
cannot receive incremental stream: most recent snapshot of zrootx/usr/home does not
match incremental source
# exit
Script done on Sun Jan 7 00:55:59 2018
I have two questions at this point.
1) What in hell does this apparently undocumented error message mean?
2) Is there still any way to recover what I need from the saved
stream? It's a couple of hundred gigabytes in length, so if it's just
junk now, I'd like to free up the space.
I think I only need three or four files that have changed since I imported
/usr/home into 11.1-STABLE from 10.3-STABLE by
dump 0f - /usr/home>/mnt/bootdisks/usrhome
on the 10.3-STABLE system, followed by
cd /usr/home
restore rDf /mnt/bootdisks/usr/home
on the 11.1-STABLE system. The rest could be reimported the same as the first
time if need be.
Please email replies to me directly, as well as to the list, because I am
subscribed to the digest form of the list, which means I might not get replies
via the list until the next day.
Thank you very much in advance for any help!
