// WORKAROUND: Script needed, because of differences in our pathfinding
// algorithm
// When the guards kick Robin out of archery room 320 the game locks up due to
// pathfinding algorithm differences. Ours sends ego in the wrong direction,
// colliding with a guard, and preventing the script from continuing.
//
// Applies to: English PC Floppy, German PC Floppy, English Amiga Floppy
// Responsible method: takeHimOut:changeState(1)
// Fixes bug: #10896
