Remove all traders/markers/spawns

[adamt 0]

When I try to remove the markers/zones/spawns in mission.sqm I face issues. This is how the mission.sqm looks like https://pastebin.com/0hS9sngJ
I remove all of the classes so I have this: https://pastebin.com/pWZWAUJj

When I join the server I never load in/spawn in, just stuck in loading screen for ever.

I solved the issue. I had to keep class item19. I do not really know why I need that class but I could figure it is the slots or something.
