Hi there!
So I went through the portal at the top of the tower to head to Nightingale.
Upon entering, I noticed the circular bramble, and thought to try my luck going around it, instead of through the tentacles.
I jumped over where I could, but was hit by the side tentacles anyways, and back tracked.
When I did, I fell through the map, but no chance of death.
There was water sounds, but I'm standing on solid ground now.
I'll need to grab a screenshot but there's a hole in the map overhead in the sewer section in southeast Nightingale.
Another unnintended exit
Idk if its the same but you can leave the intended map from behind that pillar
me too!
Adding a note that it was to the right of the circle
