Double Vaal Side areas + trapped inside one (Bug Report #1,773,693,450)

This pair of (related?) bugs occurred while performing a Zana mission. (through a selected Atlas mission) Map was a T11 Sepulchre:

• The first bug was that it spawned two separate Vaal side areas, which was supposedly fixed in 3.9.1. The first side area's portal was in the first area (the one with the ossuary tileset) and the second portal was in the second area. (the one using the Belly of the Beast tileset)
  
  
• Both could be entered and cleared, but upon attempting to leave the second one entered, (from the earlier gate) an error message appeared upon attempting to use either exit; both the original exit and the portal at the end produced this error, with the only means of exit being logging out.
  
  

The map could be re-entered from the outside just fine. Re-entering the second-used of the Vaal side areas resulted in becoming stuck again, as it was the first time around. Attempting to re-enter the OTHER (first-run) Vaal side area produced the expected message of "Cannot connect to instance." (this is recognized as correct behavior, and not a bug)

Enclosed in spoiler is a screencap of the Vaal side area (that the character was trapped in) and the appropriate error code.

Same exact thing here. T11 Sepulchre Zana mission. https://gyazo.com/6bca07446959248eac066eb54f0178ed

This is still happening as of 28/12. It's listed in the known bug reports but only that you can't get out of them sometimes ("Failed to join instances" error), but they can also still spawn more than one Vaal area in a map and that's not listed in the known bugs. I had two Vaal side instances in one map (two different floors of the map in Glacier) today.

Bug #2,302,715,884

Just got one of these myself. Happened in Temple of Decay 2. Encountered first side area, cleared it, and upon exit I was standing next to a different one, in an unexplored part of the map. I cleared the second one and exited next to it. Figuring I'd been kicked out to a different instance of Temple of Decay 2, I rushed back upstairs to try to verify that and grab bug numbers for each instance, but in doing so discovered that the map had spawned two side areas. Neither one gave me the issue of being unable to exit.
