 There may be multiple object keys in the file, each one representing one land object.
 
  * `filename`: The object’s filename (without the “.png”). Case-sensitive.
- * `max`: The maximum number of this object that may be generated in a map (must by between 1 and 32)
- * `buriedrec`: A rectangle that must be buried in the terrain (`left, top, width, height`). In version 0.9.23, if all 4 values are 0, the object will be placed on top of the water
+ * `max`: The maximum number of this object that may be generated in a map (must by between 1 and 32
