It does give you info, but info of last known location. If the enemy stands in front of the turret, it will give you LIVE info. The turret is supposed to shoot someone as it spots and will shoot a burst of 3 shots and if it spots someone for a split second it will shoot 1 shot and the rest 2 will go back to default facing position and the turret will switch to normal position.
This is where the "bug" in question comes. The moment the turret sees someone, here Omen (who was seen for a split second), it shot 1 shot and to adjust itself back to defualt/normal position it shot 1 shot towards heaven and then faced towards the generator and shot 1 shot. ANGE1 shot the turret and broke it. Pretty sure the shots were heard by the XSET players considering how sounds works in the game. The decision to keep looking at heaven because of 1 shot was dephh's to make and he gambled it and lost. Not to mention someone else who was on site with dephh was also watching heaven and trying to wallbang them (2 people looking at the same spot) while there was someone in A main (ofc smoked off).
FPX players took fight slowly despite knowing where the shots to break the turret came from, gambled wrong and lost.
