When you crouch to the edge of any ice block in the new snapshot, it takes a few seconds to stop the player completely. This is not a huge bug but it can be annoying considering how the mechanics used to work. You think you have stopped but in reality, if you uncrouch you'll slip off.

Steps to recreate:

1. Move toward the edge of a block of ice
2. Crouch at the edge
3. Try to stand back up and, if this is done too quickly, the player will slide off
