Thumbnail Doens't Work

I can’t get my thumbnail to show up on the front page. It has been happening for a while but it still is not fixed. Here’s what I am trying to get working: 1604865644876_gobo-a

But it doesn’t appear.

This happen to me too,its correct of need logo image and etc
but need tier 2(or 3)

yes. The game needs tier 2 or higher.

Also, isn’t that the Gobo sprite from Scratch? I am not sure if you can use it as you could get copyright-striked

@Kevin22 thanks for make my reply be correct
