"Undo" cannot undo arbitrary transactions but only transactions such
that no object modified in the transaction set has been modified
again after the transaction set.

You can try to undo all transactions after the transaction you
want to undo.
Alternatively, you can try "dm.historical" (to be found on "PyPi")
and reinstate an earlier version of one or more of your objects.
