Anyone knows what the heck is wrong with Kitco's gold spot chart today?

Seems to have crashed from 1680 to 1580 in a matter of seconds, followed by immediate recovery.

What the heck.

Looking at https://goldprice.org, cnbc, bloomberg, yahoo finance, marketwatch - they all have a different number for the gold price.

The spot reported is from 1,598.57 at goldprice to 1680 at other places. The charts also don't look the same.

Which one to trust?
