When crafting "Endwalker" (Brainstorm, from the bonus sheet Final Fantasy printing) I received a warning message claiming it would be rotating this Fall. I don't think Brainstorm is currently legal in any rotating format, so I can't imagine that this message is correct.

This message was separate from the warning correctly noting that the card is banned in Historic.

As the message did not prevent me from crafting, I can't imagine this bug is any meaningful priority; it would be much more relevant if the warning failed to activate when appropriate rather than activating when it is not.
