If you are checking the status of an object and that object is destroyed then the status disapears the camera breaks and your stuck looking at whatever image was there when the particle was destroyed. The objects still continue to move but the camera breaks and you cant check the status of any other particles and the UI breaks.
If you press a hotkey to spawn something there should be a transparent image behind it so you know exactly where it will be spawned when you would hold down the hotkey and then release to spawn the object. And if you click on an object from the menu then it should show up anyways and then you would just have to click to spawn it. + if you agree with me - if you don't
