MySQL warning: The SSL warning has been taken care of. This was harmless but could occur depending on your MySQL server version.
MySQL saves: The game saving system did not work properly for bungee server teleportation. If you used a bungee portal or command your saves would get uploaded as you left the server, but before the data reached the MySQL server the old data was retrieved as you joined the other server, effectively resulting in overwriting your previous saves if you had played a saveable game.
This has been taken care of and saves are now uploaded when you close the Pocket Games inventory and the retrieval has been delayed a second when you join. This will ensure that there is plenty of time in between bungee server switches to both upload and retrieve the correct data. This is still done asynchronously as to not impact performance!
Command fix: The aliases for the /pg play/highscore command were messed up. Instead of being ("highscore", "p", and "h") they were written as ("highscore, p, h"). This has been fixed.
Multiplayer fix: If the timing was just right and a player left the game at a certain moment the plugin could throw an NPE. This was harmless but has been fixed.
