The sync on Nearblocks stopped about an hour ago, causing a delay in the sync of the "Mintbase Indexer" which is used for users to check their NFTs.

As a result, there may be a delay in seeing updates in the wallet when a trade is completed or canceled.

Please be assured, there is no issue with the contract or transactions themselves. Once the Nearblocks sync is back to normal, you’ll be able to see everything in your wallet again.
