This was meant to happen on purpose because of a glitch that players did were it allowed them to equip a weapon for example a pbp shotgun, and after doing the glitch you could have flew across the water and use the weapon. I learned this after it happened to me, I killed a big crab (the summer event ones that gave you the red crab claws when you killed them) and the guy who spawned it got angry and chased me across the Ocean killing me using this glitch.
