2:11 AM] Patrick: The game has a weird way of determining whether a gf is at home:
[2:11 AM] Patrick:
// get current hour (ignore minutes)
3@ = current_time_hours, 4@ = current_time_minutes ;
4@ = 3@ ;

// """round down""" to the neares even number
4@ /= 2 ;
4@ *= 2 ;

// check whether she is at home
if( 08B6: test $383($GIRLFRIEND,6i) bit 4@ ) {


Katies has these bits set:
0 2 4 6 8 10
So she is unavailable from 0:00 to 11:59
[2:11 AM] Patrick: It is so weird, I first thought I was stupid and so I got a log of it happening.
