Langmar's Estate Instance bugged (10/17/2018)

[Fearmy.1729]

I was running guild missions last Saturday and we were about to start doing the Langmar's estate puzzle, but instead of allowing me to spawn a flag and enter the instance, the door in the open world map opened. I assumed that this was perhaps a bug that allowed us to do the mission the old fashion way so we went through the estate and completed it, but the mission did give us credit. We came back later and the mission worked fine.

I posted all of the screenshots that I took of us going through the mission here.https://imgur.com/a/NFGgRBf
