I am aware that the current implementation of Construct 2 requires at least one instance of very sprite before the game starts. I usually create a dummy DefaultLayout which is not used that contains all the default instances.
I created a sprite with Physics behavior and set its Collision Mask to circle on the first instance of it. I then went to another layout and dragged a new copy of the Sprite, however, it's Collision Mask was reset to "Use Collision Polygon". Shouldn't it have the config variables that I've setup initially? Those are considered the default values for every additional instance, right?
Somehow I seem to recall this being a bug several version back sub v90, but I'm using v102 right now.
