Why is noone complaining about this Movable Type bug ??

Movable Type 5.2.2.  Trying to mark comments as spam from the comments RSS feed - clicking on "junk".  Multiple spam messages on the one entry, so multiple attempts to publish to the same entry.  Get these errors:

Renaming tempfile '/path/to/page.html.new' failed: Renaming '/path/to/page.html.new' to '/path/to/page.html' failed: No such file or directory

And then the page is deleted until I go into the entries management and republish it.

This is so fricken fail.  And yet I can't find anyone talking about the same thing, other than the odd comment in people's blogs where people have obviously had the same problem when commenting on an entry at the exact time as someone else.
