Hi MdRuz. I use this on my other mod, Team competition, where nauvis is just a team login area. Nothing should happen there.
But by default, the mod will only spawn disasters on nauvis. You can change that adding or removing surface names by remote command:
if remote.interfaces["bigmonster"] then
remote.call("bigmonster","add_surface","game_surface")
remote.call("bigmonster","exclude_surface","nauvis")
end
If you need something else, let me know
