Hey Frank,
We have the following bug logged for this issue
Bug 29363 Sequences of straightforward operations via Python API fail when
in Undo group
Sorry for the inconvenience, that's a pretty bad bug from the Hiero days by
the looks of things. I'll escalate this internally as we should try and fix
this.
