When your in the water you can no longer create ice and get up out of the water, when walking across an ocean and fall through you have to swim the rest of the way, get to shore and start over. Jumping around in the water doesnt help, nothing works, tried reloading, taking them off and putting the mback on. Nothing helps, I downgraded to 1.14 via an alt hard drive and it works fine in 1.14
