Question - stuck in a level

Hi

I opened a map that I think I got from a Cartographer and it jumped me to another level.

I’ve cleared the level and there is a green dot where the exit should be but there is no green vortex. How on earth do I get back to the level I was on?

Cheers

On carto maps green dot is where the carto is, once you killed it, it will drop a map 1 floor higher. That’s how you go out, open the dropped map or just stay with usual map floors. Its up to 200.
