When you search it, in the side you can see a blurry, red animated circle. Clicking on it may cause nothing except the circle(I think) changing the size a bit.
The red dot is pixelated too - the animation seems to be shrinking and growing. Clicking it makes no result, however, it is an easter egg. (Do we think I might dream about planning to make the circle, if clicked, makes planes hover and destroying anything that reads 'War Thunder'?)
If the Easter Egg is identified as easter eggs, then it's true. If it's a bug, then maybe I've got it wrong or someplace else.
