Multiplayer:
----------
Players connecting to a multiplayer game are now unable to click the "Play" button until their synchronization progress reaches 100%. This was done to avoid a scenario where there would be a duplicate unique identifier created for a creature.
Players connecting to a multiplayer game will no longer receive their creature as a creature already existing on the server if they enter the game with a creature before the initial synchronization of creature data is finished. This avoids a duplicate creature being created on connecting clients.
