Dear Korvek, what you were able to do with the mighty script is mind blowing really. You do what seems impossible. So first of all : Thank you for this amazing piece of work.
after starting my first map, I have a little concern. the creature Portal seems to spawn also randomly across the map. I first thought, there may be another one near my dungeon, but there was only the fellow folks of the overworld waiting for me and I only got a few beasts from the arena.
After this I restarted the map many times until I was satisfied with the position of the portal.
My question is : was this intended? You might want to spawn the portal not too far from the players dungeon.
