 Because of the feature, chunkymap-regen.py must prevent duplicates based on value of id in the resulting yml files (minetest player filename as id).
 This should be hard to corrupt since id is used as the indexer for the players dict (however, extra files with no matching entry in the dict will still need to be deleted if they exist)
-* games_path and mods_path should not be stored in minetestmeta.yml, since otherwise the values may deviate from the parent directories.
+* games_path, mods_path, players_path, and other subdirectories of the major ones should not be stored in minetestmeta.yml, since otherwise the values may deviate from the parent directories when the parent directories change.
 To avoid this problem, instead derive the paths from the parent paths using your favorite language such as in the following examples:
 	games_path = os.path.join(minetestinfo.get_var("shared_minetest_path"), "games")
 	#KEEP IN MIND: gameid in world.mt is the name of the game FOLDER (NOT the name variable in the folder's game.conf)
 	mods_path = os.path.join(minetestinfo.get_var("game_path"), "mods")
+	players_path = os.path.join(minetestinfo.get_var("primary_world_path"), "players")
 * Keep in mind that gameid (in game.conf in a subgame folder, and world.mt in a world folder) is NOT case-sensitive: for example, minetest_game has the gameid 'Minetest' (first letter capitalized) but the worlds generated by Minetest client have the gameid 'minetest' (lowercase) in their world.mt
 * the map update function is only able to detect new chunks, and only checks edge chunks if player is present in one
 * The following are saved to chunkymap.yml if not already set:
