Trying to import various versions of recovered xmls to rebuild my tree, when there are duplicate nodes, they dont show up, but the file size appears to include the entire import

I cannot reproduce this with the current version. Please try again with 0.99.51 that I am about to release and if still happens provide data to reproduce the issue.
