Hat Troubles

So I see this awesome hat on sale in the crowns shop.

"Cool!" I say, and then I look even closer,

"I can buy it with gold too! Great!"

So I get 22,000 gold.

I change it to the cheapest colors.

I press buy.

Then I get this error message.

What?!

So I say, "Okay, maybe those two colors are glitchy. I'll come back later."

I get 3,000 more gold.

I change it to a different color combo.

I press buy.

I got the same error!

Nooooooooooooooo!

Me. want. hat.

*sniffle*

(Okay now for serious, has anyone got this error before? Can I do something to fix it? Or are my dreams of having this hat I doomed?)
