Tried out your method using the base64s and it still had the same errors.
(Here's the screenshot of the error in DevTools in case that helps since i forgot in the original post)
The error always happens when the game is switching layouts, could there possibly be an effect when Load Image is used while switching? The action is only on a trigger event so I don't think the problem is that it's happening too frequently but is there a limit on how many times you can call that action before it starts having issues?
