8. Improved team balancing logic and fixed some cases where it wouldn't be done at all.
9. Balanced Predator Smart Disc and Plasma Caster weapons.
10. Fixed clients not always being correctly notified that the game had ended.
11. Fixed the lobby timer not always displaying correctly on clients.
12. Fixed a Predator in multiplayer cancelling their lock-on causing lock-on to be cancelled for all Predators in the game.
