The weekly exchanges I did last week in the manage currency UI stopped working after this weeks reset.

Dark spirits greed: Cant exchange for the supreme cooking/alch utensils

Battlefield token: cant get the superior blue whale tendon potion.

Plump coelacanth: Cant get the courser training box, magical shard or enhancement help kit

They all show as available but when trying the exchange I get the message "This item can no longer be exchanged."

This happened again this week. Made the exchanges on wednesday evening several hours before the daily reset. They all show as available today but they all give the error "This item can no longer be exchanged.

This has been happening for ages before maintenance. After the maintenance happens it works again, I exchanged them recently.

Same. I've just been waiting until right after maintenance to try exchanging anymore.

I made this post after the maintenance. I had to wait a full week for them to start working again effectively missing 1 reset.
