Infinite Horde?

I’ve started up the latest experimental, started a new game with hordes turned on, and, I’m not quite sure why, but, even if i were to use the Debug console to travel into the blackness by about 5 155x45 Overmap screens, on the map there is s till this indicator that " OHHEY HORDE!", and it seems to be that same way on the ground too, not sure if this is a bug or not, but it VERY much seems to be one.
