Players report they are being attacked in shallow waters and even through land as sharks are clipping through the surface. In some cases players may be dragged under the world though they should be returned to the surface when the shark lets go - please let me know below if you are not.
Sharks may also attack rafts on the beach or clip through ships.
There are no gauranteed workarounds for this issue however saving the game while the shark is in the shallows or under your island may reset the shark to their default position for a time.
Players have reported that simply sleeping may be enough to reset the position of the shark (especially it it’s under your island) and we have also heard a storm may reset them too.
Please let me know if you have been trapped under the world, if sharks have attacked your beached raft (and if you were on it at the time) or if a shark has clipped/swam through a ship to attack you.
