We had a freelancer develop an animation for us, shown below: 
When I publish this to wolfram Cloud, some strange errors are introduced, shown below: 
Does anyone know what might be causing this? I thought that some potential causes are:
- CDF was developed in wolfram 12, but I published it using 11.3 student version. (unlikely since the animation ran perfectly on my laptop / locally)
- I only have wolfram cloud basic subscription, so some functions may not work
- Dynamic content. When i run on my laptop, I have to enable dynamic content. Could this be a potential source of the problems?
