momepy.Courtyards throws error with multipolygons

[ale-v]

Althouhg momepy.Courtyards has a built-in function to avoid errors with multipolygons, it does not seem enough. Here is the traceback of the error:

AttributeError                            Traceback (most recent call last)

I sense that it is the data issue. Can you share the bit of data causing a trouble? And the rest of your code including affecting this? In theory there shouldn't exist a MultiPolygon at this moment.
