Under textures

Today, a friend and I were testing out the new Battle Royale mode. We took a tank, and after a while, we were blown up by an RPG. At that moment, we most likely hit a hill and flipped over. It doesn't matter whether the tank exploded or we jumped out. We fell through the textures and were able to move around the entire map using the swimming mechanics. Please fix the collisions of the objects.
