Hi there,
Does this count ?
Seer Marino's arc, "Steal research from Legacy chain" (through ouro), same door as previous mission (inside the arachnos-controlled building) - marker tells you it's 10 feet away, click the door, back on Mercy's streets. Good. Now what. Oh heh, the marker is now behind you, telling you to get back inside from where you were. By some sorcery that even the Mu can't understand it tells you again you have to go out of the building, and that could have lasted for a good while.
Used the Mission Transporter and it brought me to a totally different door, next to Dr. Creed. And it seems the marker has realigned and shows the correct door this time.
