For what I can see, all the files are in the right locations.
The content of the nob-file(MyMaps.nob):
Chroniclesmymultiplayermap.nsc
Levelsinside.log
inside.nil
outside.log
outside.nil
outside.~ni
Scenesinside.nsd
outside.nsd
And the content of "mymultiplayermap.nsc":
#location name nil nsd mapinterface maplocator flags
location Outside outside.nil null null null 0x0060
location Inside inside.nil null null null 0x0060
exit Outside, 1 Inside, 0
metafile MP_Salon.nmf
flags 0x6
I've checked for typos but I can't find any.
I can test the map in Embrace(Run Level), but "Run Chronicle" doesn't work. The playerstart0's are all there.
EDIT: I made a new project with new maps and "insidemap.~ni" seems to be missing in the Levels-folder above. However it didn't work with this new one. At least the graphics now stays the same.
