I have a question When i make a new map on notrium and then add it to areas.dat it stops the game from booting up
The first thing you need to do while ironing out crashin' bugs it to search for blank spaces before end_of_file;.
Having any blank lines will cause the mod to, well, not run.
Next step is to look at all identifiers of new stuff, make sure the map number is right and the area identifier isn't used by any others.
Now, look at all the blocks in areas.dat and make sure it has all the blocks and lines in the same order as the previous map. Also, areas is the only file where the identifier comes before the name, so watch out for that.
