Currently, when the player uses the Ice Rod in an area where the water leads to a transition without the flippers they get stuck in a drown and refresh loop.
Potential solutions:
Block off access to transitions before the flippers are obtained.
Make drowning hurt the player, leading to a death loop on transition.
Prevent the Ice Rod from creating a walkable ice tile at the edges of an overworld map.
The Ice Rod ability is being deprioritized for water traversal in favor of Deku Link hovering via Deku Flower, so the transitions are not as large of a concern ATM.
