Steps to reproduce:
1. Run the test
2. Move the mouse around
When the sprite is rotated beyond 90 degrees from 0 it stops rotating
It should keep rotating since r=1
If you disable the event with the angle check and enable the one with mouse button check it works as expected.
I had the same problem if I used the "Is within angles" condition.
