I think I found a bug related to how AI attacks are handled in the game. When an AI attacks you, your integrity and firewall drop immediately, before the animation is completed. The same goes for when an AI steals your money - it drops down to zero immediately after the attack is started.
This doesn't seem right, given that when the player attacks an AI, the AI's integrity and firewall don't drop until the attack is finished. The same goes for stealing an AI's money - the money isn't available for you to use until after the transfer is completed.
I will look into this, but I can assure it doesn't change the balance/outcome of the game in any way.
