How do I fix this selection issue?

I have an invisible sprite that works like an RTS camera.

However whenever the sprite overlaps a building sprite I can no longer select that building in game.

I've tried changing the camera sprites size,

moving it to a lower layer below the building,

changing the camera to a tiled bg or particle effect,

changing the building to a tiled bg.

Nothing works!

It's frustrating when the player can't select a building in a citybuilder if it's on the center of the screen!

Please help!

Putting an invisible sprite over something doesn't stop it from being clicked so it must be something in your events.

Turns out the problem was in the events after all.

I had a condition that the player cannot select a building while the cursor is over a menu button. I use the same sprite for all buttons, and while the main menu is invisible during gameplay the buttons are still there. I was blaming the wrong sprite all this time and now feel like a complete idiot. xD

Thank you so much lionz for pointing me in the right direction!
