[CHAOS] Doors and Maps not loading

[Imevil23]

So, i've recently just started on my amnesia map again and want to add some detail and need help on some issues:

• How do I have the level doors show the location of the next map in game?
  
• When ever I try out my map, it crashes when I go to the third map. It says: FATAL could not load map

Any advice would be very appreciated.

*NOTE* I've fixed the issue with map not loading. I figured out that I never even set where the door leads to in the first place!
