Describe the bug
ArtemisLib allows the player to be differently sized. Using Gulliver Reborn, or Resizing Potion, players can become larger or smaller than the usual 1.8 blocks high. But when swimming with sprint, players will always end up the same size.

There's a little bit of freakout when popping in between the two, but nothing like what happens with SmartMoving.

Versions

Other
Currently only tested in singleplayer.

Should be fixed with v1.5.1.
