Well, I'm creating a world, and I have it created and everything. I downloaded the default thumbnail off the internet, and it fits the requirements. I have it in the thumbnail spot, but the game doesn't recognize it! Only half of it is in the spot (Which I thought was weird, but not the cause) with a black space underneath it.
Please, please help, because this is for a school project video and I need it done by tonight.
Thanks to everyone in advance.
