title: Appinventor : Property setter was expecting a com.google.appinventor.components.runtime.ImageSprite component but got a String instead
body: <p>i'm currently working on a Naughts and Crosses game in MIT App Inventor 2, and have run into the error in the title, i believe i've narrowed it down to a specific block of my code (the easyBot procedure) but i cannot isolate the issue from there, i have provided source code for perusal, can anyone find the issue here?</p>
