Bot - Error Types
There are currently 3 errors but only 2 of them are kind real ones.
The reboot error just makes a bluescreen and causes the bot to reboot. While the crash error causes damage to the bot.
Like i said, its only those 2 which can actully occure, the highjack error is more like a reboot error but doesent occure at random.
It pretty much forces the bot to disconnect from the current botnet and reconnect to the attacks botnet. It cant be changed back till the time runs out.

In the illegal job config there is whole explenation on how to change those errors.

Usally error occure at a radom interval but there are jobs like "The Datacenter" which trys to simulate counter attacks.
So in its config you got like every 25-40 seconds a error event that needs to be fixed somewhere between 3-5 seconds and which can impact multiple bots.

In those error events the extra value depends on the error type for the "Crash" error it means on how much damage will be applied. Since most bots dont have that much health a damage value of 50 would be fatal.
