[carl.l.stanley]

In game 70133801, at around 36:00 minutes, the Drifter used stalker's mark to teleport to an enemy who had just retreated into the Archmother base, but instead teleported to a space under the map's geometry and went out of bounds.

He teleported back after falling a good distance into a corner just outside the Archmother's base.
