About the map, I still don't understand how the map.dat works... What I have understood is that either I specify what map will appear, or I specify what area class. But the first time I tweaked the file, Notrium crashed, so I decided to leave it behind for now...
Now, this confuses me. You don't specify what map will appear, you specify an area class. If you want an area to no matter what spawn there, than you need to give that area a unique area class
2;//width of map below
3;//height of map below
An area with class 3 would be where the 3 is. Presumably there are two areas with class 2, so they would spawn in a random position out of the 2 places there are 2.
-2 means that any area can spawn there if there aren't enough specific class placements on the map.
