@Koochi-Q interesting. I think there are 2 ways for the bracelet tactical to fail. One is when the bracelet intersects an invisible hitbox that may have the wrong size or settings, resulting in the tactical failing silently. The other one is when the bracelet falls in a spot where the legend's simulated hitbox intersects with the map slightly, forcing a decline for the tactical.
My dev instinct tells me that the areas where Loba's tactical fails are also places that swallow Gibby's and Caustic ults or prevent gas cans from getting triggered.
Aaanyway, got a really bad bamboozle by Gibby while playing Loba, which might indicate a rare @ low prio bug. The 5th-6th ring was closing, I was basically out in the open, while the enemy had snipers and higher grounds, so my only safe way was to throw the bracelet near a rock that's at the edge of the next round. To my surprise the moment I teleport, I hear Gibby's ult somewhere in the vicinity, only to get bombed to death. What happened? Well, the game actually triggered Gibby's Ult sound considering my position before teleporting, but then that sound did not get adjusted for my new position, making me think I'm safely outside of the bombardment zone.
