Overgrown Ruin Vaal-Side-Area-Bug

While running a Tier 12 Overgrown Ruin Map, i encountered an unnatural high ammount of vaal side areas, see attached image.
You could run them, but upon completing them you couldn't use the portal back to the map (Transfer to this instance is not allowed using this method.) which forces you to log out.
When relogging the map was still playable.

Also happened to me in a tier 3 overgrown ruined. The first vaal side are let's you complete it but any after that bug out and you have to log out to get out of it. Game is full patched up
