Dalamud Minion Code [Dev Response Request]

[Cigaran]

See this is why I want to know if the code might still be valid.

You're not likely to get a response on this and it'd be even less likely for a developer as it's not their thing to handle. If CS comes on and says "Yeah sure." and your code works, after the clearly printed and stated expiration date, then CS is going to have to honor that for every single item code they hand out.
