'Disable collisions' only affects 'On collision' and 'Is overlapping' events. Arguably a touch is not a collision, because the touch is not an object that is colliding with it, it's something else (a form of input). So I'm not sure if this should be changed anyway?
No, I think that would cause issues. My point is since Touch is also dependent on Collision Polygons, I think adding in the manual that touch is based on collision polygons but not applicable by events nor object collision would suffice. This is a simple misunderstanding but if somehow some people will make a big game and somehow missed this, then it would be a big problem.
