Rafts can't get near Crab King (unless their collision go bonkers)

The first screenshot is a case where it's impossible to attack or row closer to Crab King, which I think (and wholeheartedly hope =) ) is unintended. Visually there is still room to row towards Crab King and attack from the raft, but the raft won't move any further.

The second screenshot is a case where the raft was so close that it broke the raft mechanics and separated the walkable platform from the raft itself. Ice shield spawning on top of close boats/rafts is pretty common too, but this felt like the extreme case where things are completely unintended.
