Does NC still expire after a year?

[Slumber]

It occurred to me I think I've had NC untouched on a few side accounts for quite a while but haven't gotten the usual expiration warning NMs. And I haven't been spending or buying new NC on those accounts so there's no 'turnover' of NC.

Does NC not expire anymore? Is there a way to check for when your NC expires?

[Suicune]

yes it does

I believe you get crappy items instead
