Cursor Over Event not triggering

Here’s what I have in the level right now: a player controller and gamemode blueprints, overriding the default ones. Mouse over events are turned on in player controller (every mouse event is, actually).

Just closer to the point: I have a simple static mesh and a class blueprint with a mesh attached, both having a ‘Mouse Cursor Over Begin’ event which is printing the test string. The thing is: mesh event is being triggered and the BP’s one isn’t. I checked the properties of a mesh, attached to a BP, and it has Collision Presets set to ‘Block All’.
No clue why it isn’t triggering =(

Well, I just dealt with the problem, sort of. Got my event working by deleting the scene root component out of Class BP, but now my mesh seems to spawn with just default scale values =(
