+Subject: [PATCH] Only fetch an online UUID in online mode
+
+The previous code would get an online UUID even in offline mode that
+breaks plugins if the player joins.
+
+Example:
+You want to store data for player "Test"  who never joined. An online UUID is created and you save it using that UUID.
+
+The player Test joins with an offline UUID but that will not match the online UUID of the saved data.
