MovementManager.GoUnderwater

My english is bad and I cant edit the first post, I mean this function replaces mouse cursor in a random position on the screen

Hey, I use only lua api I don't know why this move your cursor:

public static void GoUnderWater()
{
  Lua.LuaDoString("MoveViewUpStart()");
  Thread.Sleep(1000);
  Lua.LuaDoString("MoveViewUpStop() MoveAndSteerStart() MoveAndSteerStop()");
}

I disabled "Hardware Cursor" and the problem was partially resolved.
