In Glyphs 3.303 rotation actions as scale

When I attempted to rotate a gluph to 180 degrees, it instead scaled up to 250%, repeatedly.

where/how do you do the rotation?

For 180°, I usually mirror horizontally and vertically with the two mirror buttons in the Transformations panel.

I did my rotation in the transformations panel as I have done thousands of times with no problem prior to this release.

I can’t reproduce it. Can you send me a screencast?

What is a “Screen cast” ?

I meant screen recording. You can do that in the Quicktime player app.

Now I cannot reproduce it either. I don’t know what changed in 2 days?
