There is a bug that comes up at random that adds extra frame of 1px width to the sprite ( at least that's how it looks like; sometimes in image editor from which you can't remove it, and other times at runtime) but not to collision mask. It's impossible to reproduce since it's... random.
Also, they're both solid objects, so they can't overlap. "Is Overlapping at offset" produces random gaps for no reason.
Would it really be that hard to make the action anyway? Doesn't the engine already check collisions for everything?
