Vandal alert notifications in Ideas Posted April 3, 2016 · Report reply Found the relevant code. It seems that only angry peeps vandalize, and only when there is no security guard within 7 tiles of the peep. The sprite that is shown in the window is decided here - the angry face is shown if var_F3 is nonzero. var_F3 is set to 16 when the peep vandalizes a path object, and decreases by 1 on each update until it is back to zero. I am not sure if this unsets the angry flag or not. So it seems that the red face is shown only once a peep has actually vandalized an object - angry peeps that have not yet vandalized (or have gone long enough without vandalizing) are not visibly angry. Also interesting is that naming a peep "Eilidh Bell" will instantly make them angry.
