There is a problem with the blank ground map of Vulcan. the map is off and only a section of the map can be viewed when you try to enter the area where the main public section is at (i.e. the temple and stairway..) you are blocked from doing so.
please fix this soon if you can as this was one of the maps i wanted to use.
I must say i like the feature that you can change the sky settings though very nice!
EDIT: it seems the default spawn point is in the area you normally can go.. its just that the 2d map is not showing right which is causing problems for placing objects and such. thanks!
