Object simply vanishes when resized

Hello DiarmaidCollins,

Thanks for bringing this to our attention! 

I can't replicate this behavior using a new project with simple images, which leads me to believe that a combination of multiple triggers and slide objects could be causing the glitch. Would you be willing to share a copy of your project file here or in private by opening a support case so I can take a closer look at how the slide was set up to identify the cause of the glitch? We'll delete it when we're done testing!
