The title says it all. Soul sand is known for slowing anything that walks on it. This slowing effect used to be amplified if Ice, Packed Ice, or Slime blocks were placed under it. Now, this feature has been removed. This has caused some significant issues for one of my builds, and I'm sure that this has affected other players as well.
