I have a decal here (It’s 1024x1024) 
When I upload it to the Roblox website, I am given a 400 Bad Request error. I thought the limit was the 1024x1024. Has it been lowered?
Update: I’ve downsized it 512 x 512 and it won’t upload now. What is going on?
I am thinking it might be the name of the decal? Maybe try changing the name or try uploading the decal from studio and check if there are any output errors there. Generally it will give a more concise response.
Yeah, the name bux was moderated. Thanks.
