=== Extra Information Array ===
Note: the sum of all ItemProbabilities should be equal to 100.0.
if ref_extra does not equal 0 there is an extra_info_array attached to this area. The array is 4 or 8 values long.
 
Every area includes a [[HGHT|.hght]] and [[MATE|.mate]] file. The extra_info_array indicates if there is an additional [[Water.extm|.water.extm]] and / or [[Grass.extm|.grass.extm]] file
