NMS Custom Entities HELP :(

Hi there! As the title suggests, I'm trying to make custom entities using NMS. I've looked up every tutorial I can. The custom entity correctly spawns and has no behavior, as desired. However, whenever I try to set it's pathfinder so it'll move, it does absolutely nothing. It won't walk to that location.

Here's my custom entity:

Code (Text):

@SuppressWarnings( "rawtypes" )
    public CustomZombie(org.bukkit.World world){
        super(((CraftWorld)world).getHandle());
     
        List goalB = (List)nmsUtils.getPrivateField("b", PathfinderGoalSelector.class, goalSelector); goalB.clear();
        List goalC = (List)nmsUtils.getPrivateField("c", PathfinderGoalSelector.class, goalSelector); goalC.clear();
        List targetB = (List)nmsUtils.getPrivateField("b", PathfinderGoalSelector.class, goalSelector); targetB.clear();
        List targetC = (List)nmsUtils.getPrivateField("c", PathfinderGoalSelector.class, goalSelector); targetC.clear();
     
         
    }
 
    @SuppressWarnings({ "rawtypes", "unchecked" })
    public void walk(Location l, double speed){
        /*try{
            Field gsa = PathfinderGoalSelector.class.getDeclaredField("a");
            gsa.setAccessible(true);
           
           
            gsa.set(this.goalSelector, new UnsafeList());
            gsa.set(this.targetSelector, new UnsafeList());
        } catch (SecurityException e) {
        e.printStackTrace();
        } catch (NoSuchFieldException e) {
        e.printStackTrace();
        } catch (IllegalArgumentException e) {
        e.printStackTrace();
        } catch (IllegalAccessException e) {
        e.printStackTrace();
        }
*/
     
        this.goalSelector.a(0, new PathfinderGoalFloat(this));
        this.goalSelector.a(1, new PathfinderGoalBreakDoor(this));
        this.goalSelector.a(1, new PathfinderGoalWalkToLoc(this, l, (float) speed));
        //this.goalSelector.a(2, new PathfinderGoalMeleeAttack(this, EntityHuman.class, this.bI, false));
        //this.goalSelector.a(3, new PathfinderGoalMeleeAttack(this, EntityVillager.class, this.bI, true));
        //this.goalSelector.a(4, new PathfinderGoalMoveTowardsRestriction(this, this.bI));
        //this.goalSelector.a(5, new PathfinderGoalMoveThroughVillage(this, this.bI, false));
        //this.goalSelector.a(6, new PathfinderGoalRandomStroll(this, this.bI));
        this.goalSelector.a(7, new PathfinderGoalLookAtPlayer(this, EntityHuman.class, 8.0F));
        this.goalSelector.a(7, new PathfinderGoalRandomLookaround(this));
        this.targetSelector.a(1, new PathfinderGoalHurtByTarget(this, true));
        this.targetSelector.a(2, new PathfinderGoalNearestAttackableTarget(this, EntityHuman.class, true));
        this.targetSelector.a(2, new PathfinderGoalNearestAttackableTarget(this, EntityVillager.class, false));
    }

Here's the my custom Pathfinder goal class:

Code (Text):

public class PathfinderGoalWalkToLoc extends PathfinderGoal{
   
    private double speed;
   
    private EntityInsentient entity;
   
    private Location loc;
   
    private Navigation navigation;
   
    public PathfinderGoalWalkToLoc(EntityInsentient e, Location l, double speed){
        entity = e;
        loc = l;
        this.speed = speed;
        this.navigation = (Navigation) this.entity.getNavigation();
        this.speed = speed;
    }
   
    public void c(){
        PathEntity pathEntity = this.navigation.a(loc.getX(), loc.getY(), loc.getZ());
        navigation.a(pathEntity, speed);
    }
   
    public boolean a(){
        return true; //should start? add a range check here
    }
   
   

}

And here's my nmsUtils class, where the reflection takes place:

Code (Text):

@SuppressWarnings("rawtypes")
    public static Object getPrivateField(String fieldName, Class clazz, Object object){
        Field field;
        Object o = null;
       
        try{
            field = clazz.getDeclaredField(fieldName);
            field.setAccessible(true);
            o = field.get(object);
        }catch(NoSuchFieldException e){
            e.printStackTrace();
        }catch(IllegalAccessException e){
            e.printStackTrace();
        }
        return o;
    }

And lastly, here's my EntityTypes enum thingy:

Code (Text):

public enum EntityTypes {
   
    //NAME("Entity name", Entity ID, yourcustomclass.class);
    CUSTOM_ZOMBIE("Zombie", 54, CustomZombie.class);
   
    private EntityTypes(String name, int id, Class<? extends Entity> custom){
        addToMaps(custom, name, id);
    }
   
    public static void spawnEntity(Entity entity, Location loc){
        entity.setLocation(loc.getX(), loc.getY(), loc.getZ(), loc.getYaw(), loc.getPitch());
        ((CraftWorld)loc.getWorld()).getHandle().addEntity(entity);
    }
   
    @SuppressWarnings({ "unchecked", "rawtypes" })
    private static void addToMaps(Class clazz, String name, int id){
        ((Map)nmsUtils.getPrivateField("d", net.minecraft.server.v1_8_R2.EntityTypes.class, null)).put(clazz, name);
        ((Map)nmsUtils.getPrivateField("f", net.minecraft.server.v1_8_R2.EntityTypes.class, null)).put(clazz, Integer.valueOf(id));
    }

}

Any help is greatly appreciated!
