📋 About This Mod
Fixes (https://bugs.mojang.com/browse/MC/issues/MC-220390) a bug where if you hit an entity while swimming and holding the sprint hotkey, the hitboxes server and clientside will be different. Resulting in weird behaviour where the client thinks that theyre swimming while the server doesnt think that. So when you for example try to go into a 1x1 block space while experiencing this bug, you will glitch out until you stop swimming and swim again.
The bug really annoyed me in monuments so I fixed it.
