Avoid multiple AIs all issuing orders in exactly the same tick.

Browse Source 
Randomize the initial tick used for each AI so they don't cause lag but all flooding the same tick with orders, but instead (try) and use a different tick for each AI. Order processing is expensive due to the need to sync world state, so it is best to spread out the performance cost of issuing these orders over different ticks.
