Hello,
Me and my friend were testing what would happen when you remove the ice from the feet of a player and find out the following exploit/bug:
1) This worked when almost all the ice was melt but some small bits were still up.
2) A player standing on the ice tile dig the ice below his feet, if surrounded by water tiles he will be stuck, floating on the water with an iceblock on his head.
3) At this point another player with a boat get close and let him drop the icecube he's lifting on his head into the boat
4) Now the player floating on the water is free to walk around like a jesus
If required I have a video of the following process
