Missing Avalon Gate Missions?

The ones where you utilize your trained squires to assist and fight alongside you? There was even a translated NA Mabinogi Splash Page where you can view the whole thing, plus it's a Lv60+ requirement.

I'm past that level and don't see any mention of it, as a result I'm holding back on rebirthing with one of my four rebirth potions until I'm sure.

Edit: Found some information, after googling a bit, there's a /baltane url that was still saved in my url history but the page is removed, and googling that url brings up a forum thread on it with more info. http://forums.mabinogi.nexon.net/discussion/14335/what-happened-to-the-baltane-mission-teaser

Chain Slash is a two-part update.

This first part is the Scenario with Eiren and the other Aces that introduces the first 10 Chain Slash skills.

The second part is going to come later, and it will include the final 3 Chain Slash skills, as well as add in the Baltane Missions. It seems they accidentally put up the teaser micro-site for the Baltane Mission Update part of the Chain Slash Update and then took it down later. But it's definitely still on its way.

There doesn't seem to be a set date, but it should be sometime fairly soon, perhaps within a week or two.
