+Subject: [PATCH] Fix "Not a string" Map Conversion spam
+
+The maps did convert successfully, but had noisy logs due to Spigot
+implementing this logic incorrectly.
+
+This stops the spam by converting the old format to new before
+requesting the world.
+
+Track spigot issue to see when fixed: https://hub.spigotmc.org/jira/browse/SPIGOT-6181
