   Hiya @nono,
   
   This looks like either something was creating its own revisions or there was an accidental copying of revisions between documents that were then inserted using new_edits=false. A subtlety of the tree is that the the revision identifiers only have to be unique at the node level. Generally they're unique to the tree unless we get into shenangians around using new_edits=false in which case the actual constraints of the tree are much looser than what normally happens. And unfortunately a lot of the traversal algorithms assume unique revisions so when you specify them for some operations you may not be getting the one you expect.
   
   Your best bet would be to purge the 11- revision so that you're back to a linear history and then move on. In the future I'd avoid using new_edits=false in application code.
   
   Paul
