Question about model icons

[Fawfulthegreat64]

As of recently, I've begun making the small icon for my custom models animated. This seemed to be fine the first couple times I did it, the model was approved with the animated icon. So I decided to adopt a turntable format for icons going forward. But my last two submissions had the animation removed from the icon when they were approved. I just want to know where it's acceptable and where not, if it wasn't just an error of course.

These were the icons I originally included with these models (the interpolation is to avoid edge pixels being white from GIF limitations):

I don't get why it would have been removed, it looks nice with the model rotating in the preview. Was the spinning icon on both sizes of the icon?

[Fawfulthegreat64]

No just the small icon. I didn't do it with the large icon since I've never seen anyone else use an animated big icon.

not involved, but maybe it's a filesize thing? gifs tend to be huge and there's potentially a lot of small icons on a game page
