When I or a team mate have a bee in the bonnet and I use empathy or revive the bee(sticky grenade) explodes earlier than if I hadn't tried to remove it. It's probably intentional considering the insidious nature of the devs. If it is sposed to blow then maybe it shouldn't say "sticky grenade removed". "sticky grenade triggered" or "engi fail" or "u was pwnd" might be more appropriate.
