I used the Mercurial collapse command and then attempted a rollback). I now know that this is something that I shouldn’t have done.

hg status
abort: working directory has unknown parent 'e1f07eea60bf'!

The working copy contains a reasonably recent version, at least, but I can’t commit it.

hg commit
abort: 00changelog.i@e1f07eea60bf: no node!

How would you best recover from this situation? With regards to history, most of it has been pushed to the central repository anyway.

    Try hg debugsetparent xxxx, It’s not the safest command in the world, but it should help you out. Set the parent to a revision that is in your log.
