So far it seems that the ai groups spawn in a fixed ratio towards each other. When you play in peace with the trading guild they wont die but pirates will. This will lead to all AI groups being occupied by trading guild, as there is no tracking on the amount of living ai ratio.
Because of the trading guild's behavior, they can start grouping/clustering in small universes with not a lot of explored sectors. You can encounter 50 trading guild ships all hugging each other in 1 sector. This could cause severe server lag depending on the ship's sizes.
You can't really reproduce this.
