The history is already missing. It is just that bzr0.8.2 didn't notice. We do want to support your use case, though. I suppose the big question is why r156. If you were using 0.8.2, I think it is possible for it to have picked a revision history that didn't match the mainline history. I don't remember if we have an easy way to fix the revno. I think (bzr reconcile --branch).

I don't mind losing some history though, is there a way to restart the history as of some revision (like 200) as if it was the first commit, and discard the rest? It only seems to be having trouble with some of the oldest patches. - Andy On 17/10/2011, at 2:17 PM, Martin Pool wrote: > Hi Andy, > > This looks like bug 397556, which was fixed in bzr 2.4.
