Air AI

• Fixed a bug with interceptors constantly being sent to enemy air bases
• Will divert TAC and CAG to bomb invasion fleets

Production AI

• AI should no longer burn manpower when at war if it needs for reinforcement.
• Production AI: Slight tweak/bugfix for excessive building of land units.
• Production AI: Fixed a bug that could prevent proper building of ships and air units
• The AI is now a bit more conservative with its manpower.
• The AI now builds proper divisions.
• Major Powers will only build buildings once all build requests are met.

• Added a manpower check for major powers building buildings. If the AI is low on manpower the limits placed on how many buildings he builds will be removed.
• Any country that has over 50 IC will create full divisions, if they are less than 50 then single brigades will be built

Research AI
