Cyclone path-finding is not working as it should around abyss openings

When the abyss openings (the circle things monster come out) is in narrow areas and the character cannot pass through a side, it stops cycloning there and gets stucked between monsters. As one may guess this is hard to realize and act fast when tons of mobs around and for a cycloner quite deadly situation.
Here is an image of an example situation :

Here the crack is closed, this happens when it is still open. And it happened exactly where my character is in at the image.
