Did `Layer.reinterpolate()` break in latest ce version(s)?

Just this Layer.reinterpolate() bit errors in this:

Traceback (most recent call last):
  File "<macro panel>", line 18
  File "GlyphsApp/GlyphsApp/__init__.py", line 9736, in Layer_replaceLayerWithInterpolation
objc.error: NSInternalInconsistencyException - enableUndoRegistration: NSUndoManager 0x12c6314d0 is in invalid state, enableUndoRegistration may only be invoked with matching call to disableUndoRegistration

can you send me the file that is causing this? I can’t reproduce it right now.

Sorry for the delay. It seems it was broken by a script or plugin. Could not reproduce either ever since. All apologies.
