An attempt to incorporate NFTs throws a wrench into a $40 million domain name auction
Frank Schilling, founder of the Uni Naming & Registry (UNR) held an auction for 23 TLDs (the bit at the end of the domain, like .com or .org). These included
.game, and even
.christmas. The April auction grossed more than $40 million, but as of mid-December the transactions had not been completed. This is because UNR attempted to add some marketing flair to the auction by including NFTs for each of the TLDs, to go to the auction winners. ICANN, the group responsible for much of the domain world, objected to and withheld consent for the transactions, writing "we sought to understand the impact of the transactions on the Domain Name System ('DNS'), including how Non-Fungible Tokens (NFTs) created on the Ethereum Name Service (ENS) were being used, and were involved in the transactions. ICANN repeatedly asked UNR for documentation or other information related to NFTs in the hopes that UNR would provide fulsome and complete responses."

German museum accidentally burns two valuable Cryptopunks NFTs in copy-paste error
An employee of the ZKM Centre for Art and Media in Karlsruhe accidentally sent two of their four Cryptopunk NFTs back to its smart contract address. This is referred to as "burning" the NFTs, because the address is inaccessible and the NFTs are permanently impossible to trade as a result. The employee had copied the Cryptopunks contract address while browsing Etherscan, and didn't realize that was what he was pasting while making the transfer — wallet addresses are long hex strings like 0xb47e3cd837ddf8e4c57f05d70ab865de6e193bbb and are prone to errors like this since they are not easily distinguished at a glance. The two NFTs were originally acquired for the museum for approximately $100 each in 2017, and are individually valued at around $187,000 as of January 2022.
CEO of Turkish crypto exchange Thodex apparently makes off with $2 billion in investments
Turkish Bitcoin exchange Thodex halted trading and limited customers' access to their investments, claiming it was to investigate suspicious activity and swearing it was not an exit scam. With an international manhunt now underway for the Thodex CEO, and no sign of the approximately $2 billion that was invested in the platform, it seems awfully likely it was a rug pull.
