Dreamwalk Teleport not returning to previous location?

It has been a thing for quite some time that if I cast Dreamwalk in Boralus, then exit the Dreamway but remain in the Dreamgrove to use the mission table, I can cast Dreamwalk again to teleport back to Boralus.

I tried to do this a few minutes ago and all of a sudden it just brought me to the Dreamway instead of returning me to my starting location. What gives? Is this a new change? Did I run afoul of some weird no-man’s-land in the Dreamgrove that screws this up?
