C4 is broken, please fix this

I've tried using C4 to destroy a Bradley 3 times in my current match, and it's doing nothing. I don't think I'm even getting vehicle damage points, and I've put 3 on the enemy vehicle each time. Not sure what's happening. I remember there being a bug in the beta where it would only trigger 1 C4's worth of damage even after putting multiple down, shocked theses sorts of things haven't been ironed out by now. Very frustrating after going on a lengthy flank to destroy the enemy tank from behind only to have faulty C4 😂

Other than that, really enjoying the game. Please Dice, sort the C4 out.
