As far as dev priorities go, this is a way low one. The Card Collections button seems to have some odd boundaries, particularly on the bottom edge. On the image I attached, the cursor followed roughly the center of the red dots and was mostly able to consistently trigger the button's mouse over. Additionally I noticed a couple of more isolated hot zones that didn't seem connected to the rest of the area, but still managed to trigger the MO.

Yea, the boundaries aren't interfering with anything else. I'm honestly kind of amused at it's odd shaped hot zone.
