Huh, mine doesn’t do this.

I ran these commands on your draft repo and they worked without issue.

   cd blockdiag_interactive_shell\[1-draft\]/
   hg fold -r bce73b522aba:43185a19a6fe
   hg gl —hidden

One thing I should note is that all of your repos are missing changeset dfe66ec9d2b2 which was in your recent example. More generally, all of your examples contained history before and after the changesets to be folded. I added a changeset and re-ran the same test above on pristine:

  cd ../blockdiag_interactive_shell\[pristine\]/
  echo blah >> app.ini ; hg ci -m "Another changeset"
  hg phase -df -r bce73b522aba:43185a19a6fe
  hg fold -r bce73b522aba:43185a19a6fe
  hg evolve --any
  hg gl --hidden

So, perhaps it’s a bug in the windows version?
