1. Load attached repro mission "24590_explosivesRevealPlayer.Stratis" in mission editor.
2. Note the mission layout, including enemy tank location. The player is invincible for this mission. Hints show what the enemy knowsAbout you, and a red arrow indicates where the enemy thinks the player is (third person view recommended).
3. Preview mission.
4. Move toward the short Hesco barrier just inside the firing range (10m in front of your starting location).
5. Place an explosive charge near the barrier.
6. If the enemy tank has not spotted you yet, run around until it does. The hint will report knowsAbout value of 4 (although anything over around 0.2 will work).
7. Retreat west behind the concrete walls of the firing range shelters. Turn on your GPS minimap (ctrl+M).
8. Head north and follow the waypoints down the Hesco barrier corridor to get behind the tank without being spotted. If you are spotted after step 7 restart the mission. Feel free to use time acceleration.
9. You will arrive at the end of the corridor (south of the tank). The tank should not detect you, as the gunner and commander are staring at your last known position. Continue east and find a location where you have line of sight with the tank, but would not reasonably be expect to be spotted. Concealment (hiding behind a tree or bush) reduces the chance of being fired upon, but certainly does not eliminate it.
10. Wait until the knowsAbout value returns to 0.
11. Detonate the explosive. Observe the tank commander and main turret instantly swing around to point directly at you, and fire (if player is at long range or concealed, they will sometimes not fire, but they are definitely made aware of you). If the player is behind cover (eg, behind a building this bug does not occur). Note that this occurs, even though the AIs thinks the player is at the detonation point.
12. Repeat, this time setting of the explosives off before the AI forgets you. Observe the AI keep staring at your last known location.
13. Repeat, this time placing the explosives without ever being spotted. Observe the expected plausible AI reaction (they scan the horizon, detecting player only if they are looking at you).
