Update 217: fix for Stop the Siege mission not completing

Hi,

I fixed the following issues:

• Stop the Siege mission did not always complete in a multiplayer game if the same player did not kill all the spawners. If you were the player killing all spawners or if you played solo, it would still complete.

• In Guardian's Gate, the mercenary captains that spawned after an obsidian tower was defeated, did not belong to a specific player. If a captain killed an enemy and caused a marble to drop, the game could not assign it to his owner, causing an error. Unity supresses errors so the game continues to run, but unforseen problems can occur.

Till later,

André
