Not to long ago I had funny glitch on Pentagon while playing online. I was in the right side-building, the building with the hole in the ground on the second floor. I tried to go through to the hole and advance to the opponent's side.
However, whenever I tried to fall through it, the game would teleport me back to the second floor. I tried it several times but I couldn't leave. Instead I tried to use the stairs to leave, but when I reached the bottom the game would teleport me back again to the second floor.
So, I was stuck on the second floor and that is why I waited untill someone came and killed me. However when I spawned, I suddenly spawned on the "3rd" floor of the back building facing the central road/street.
When I tried to leave the floor by jumping off the floor to reach the central road/street it would teleport me back again to the "3rd" floor. I spend the rest of the game on the 3rd floor sniping people with the Phase Rifle since the game wouldn't let me leave the building.
