assert "m_indexMapping.size() == pDirectoryListing->GetCount() + 1" failed in UpdateDirectoryListing_Removed().

[ruakzilla]

I'm attempting to delete a folder with one or more pdf files in it. There are currenlty 7,854 directories in /pdfs. I've done this many times before without issue.

Ex. path. "../pdfs/347555/347555.1588361310.pdf"

The error seems to occur *after* deletion when it attempts to update the directory listing.

ASSERT INFO:
RemoteListView.cpp(652): assert "m_indexMapping.size() == pDirectoryListing->GetCount() + 1" failed in UpdateDirectoryListing_Removed().
