: So... WTF?

I don't think there's any indication that Riptide takes place decades later; reread the flavor text.

"The Created have wasted no time in extending their influence across inhabited worlds, burrowing into Forerunner machinery and UNSC information systems to turn terraforming equipment and world engines to their own grand designs. Unbound by the limited foresight of mortals, the agents of Cortana can reshape worlds into verdant gardens teeming with life after only a few decades of manipulation, but at much short-term cost. Scarred by wars both ancient and new, the Created have judged this planet to be in need of significant remediation and remodeling; shifting continents and oceans after the AI constructs carefully balanced the drawbacks and benefits of both limited extinction events and damage to the existing colonial infrastructure."

Operative word: can, and short-term cost. The world has clearly not been remediated as of yet.
