My best guess is that a undocumented event change going from Minecraft 1.21.1 to 1.21.3 and onward including the new 1.21.4 , It affects Spigot,Paper and there for Viaversion. If a coder on one of these projects, take a look here for a method change that I am not seeing src/main/java/nl/mtvehicles/core/movement/VehicleMovement.java

The problem is not in Paper 1.21.1 . Paper 1.21.1 accepts input as a vector , ViaVersion supporting 1.21.4 will only accept input as a BOOLEAN . "Player input packet no longer sends a vector, it sends a bunch of bools, you derive a vector from that, see getLastClientMoveIntent on ServerPlayer It tells you where you can see the vector derived at and allows you to mimic an implantation" .

For ViaVersion to support a 1.21.1 plugin when a 1.21.4 client logs on to the server it will need to allow vector input not BOOLEAN

The bug still exists on ViaVersion supporting 1.21.4 on Paper 1.21.1
