+Default value is 12.
 I higher number allows to build larger farms and machines which keep loaded, but increases the server load, too.
 But the areas are only loaded when the player is online.
 To be able to use e.g. 12 forceloaded blocks per player, the pararamter 'max_forceloaded_blocks' in 'minetest.conf' has to be ajusted.

+The lava/water Cobblestone generator allows to produce infinite Cobblestone. By means of Quarry,
 Grinder, and Gravel Sieve it allows to infinite generate ores.  
 This can be disabled by means of the setting parameter. If enabled, the Cobblestone 
 generator generates Basalt instead, which only can be used for building purposes.

 #### Machine aging value to calculate the lifetime of machines
-Default value is 200.  
+
+Default value is 200.
 This aging value is used to calculate the lifetime of machines before they go defect.
 The value 200 (default) results in a lifetime for standard machines of about 2000 - 8000 item processing cycles (~2-4 hours).

 - Almost all machines break after a certain amount of time (switch into the state 'defect') and have to be repaired.
 - A Repair Kit is available to repair defect machines.
 - A Forceload block (16x16x16) is added which keeps the corresponding area loaded and the machines operational as far as the player is logged in.
