Teleportation Shrine Appearing In Sorcery Perk Portal

I went into one of the orange portals that starts showing up when you’ve gotten a certain sorcery perk, but instead of a portal back, there was this Teleportation Shrine.

EDIT: The portal seems to change into the Teleportation Shrine only AFTER defeating the monster inside.

EDIT: This happens with Eternity’s End portals as well, assumably it will happen in the Swamplands shrine portal things, too.

Fixed for the next patch, thanks!
