Odd door in "Stop Longbow from Curing the Infected"

[ZorkNemesis]

In the mission "Stop Longbow from Curing the Infected" (Mercy Island, Doctor Webber) I ran into a strange hiccup while traversing this mission.  Halfway through the map you have to go through a door into another section of the map, but upon entering said door it simply deposited me back out the same doorway I had entered.  I tried the door several times and about half the time I tried to go through the door it would just spit me right back out, reminding me of the old CoT portal bug in the process.  Entering from the other side of the door did not present any difficulty.

 

The instance map this occured on is LONGBOW_SNAKE_CAVE if that helps.

I'm having the same bug. This was an Ouroboros version of the mission, if that helps.
