Some of the changes:

All Factions -

• Beam weapon damage is no longer over-applied in cases when the damage duration is equal to or greater than the update period of the damage system. (aka - fix for the Illuminator mystery damage bug)
• Fixed AI not autocasting ultimates.
• Fixed where the AI wouldn't start building anything until awhile after the game started.
• Improved the AI's building in general.
• Fixed bug where AI would incorrectly send an incomplete attack force.
• Improved the AI's ship building selections.
