What do you mean? This week is Khetar week. Of course the underspire is Khetar restriction.
Not sure when you checked the calendar, but when they were first put up, there was an issue, then players pointed it out, and they got updated. That was weeks ago, though.
And, as was pointed out on the thread, you can check the campaign artifact to see what locations we’ll be in in future weeks, as well, which is more accurate than the calendars we get, anyway.
Issued together on 1 Dec. Posted on guild discord for the team. Job done.
So, it looks like the original calendar was simply amended under the same heading and not advertised as an amendment.
So why on earth would I have noticed it.
