At the ends of episodes~209 and 210 there is a side story about a guy minting coins. He got bamboozled by his copper supplier Nasir!

The copper was not shit his copper swords and shields are the finest I've ever seen

I mean, some people might not require a higher quality copper. Maybe it was simply the customer entering the wrong grade on the ordering form?

I mean those glyphs aren't exactly super hard to get wrong. You want to write 𒈁 but instead write 𒈑.

Was this just a Karen complaining all along?

Libel is a crime, you know.
