Under The Map Exploit

While playing Conquest on King's Battery, I was killed by an enemy player using C4, but when the game showed who killed me, there wasn't anyone there. After getting back to the spot where I was killed, the same thing happened, where I was killed by C4, and the kill cam showed nothing. Going back a third time was when I saw a C4 being thrown from underground, but still didn't see anyone on radar, and did see an enemy player dropping down a hole. It turns out that's how you get under the map. Don't know how it was done, but my guess is that the destruction mechanic was used to make the hole, or the floor wasn't correctly placed. When you go under the map, there is no way out unless you get killed or redeployed, and it isn't just a stuck spot but a small cave-like area where you're able to put gadgets and have enough room to get away from any nades being thrown down to kill you while being off the radar. You're able to see clearly who is above you, but can't shoot through the floor, and C4 thrown from below doesn't do damage to anyone above, but it does to anyone who is under the map with you. I took a video and screenshots of where it is and what it looks like from under the map. Hope it gets fixed before full release.
