Some API events are not firing at all

public class EnhancedVisualEventHandler {

	static Minecraft mc = Minecraft.getInstance();
	
	@SubscribeEvent
	public static void onExplosionEffect(VisualExplosionEvent event) {
		if (!event.isCanceled() && mc != null){
			Player player = mc.player;
			if (player != null && CuriosApi.getCuriosInventory(player).resolve()
					.flatMap(curios -> curios.findFirstCurio(stack -> stack.getItem() instanceof ShieldofHonorItem))
					.isPresent()) {
				System.out.println("Visual Explosion Event Cancelled");
				event.setCanceled(true);
			}
		}
	}
	
	@SubscribeEvent
	public static void onSplashEffect(SplashEvent event) {
		if (!event.isCanceled() && mc != null){
			Player player = mc.player;
			if (player != null && CuriosApi.getCuriosInventory(player).resolve()
					.flatMap(curios -> curios.findFirstCurio(stack -> stack.getItem() instanceof ShieldofHonorItem))
					.isPresent()) {
				System.out.println("Splash Event Cancelled");
				event.setCanceled(true);
			}
		}
	}
	
	@SubscribeEvent
	public static void onEndermanEffect(SelectEndermanEvent event) {
		if (!event.isCanceled() && mc != null){
			Player player = mc.player;
			if (player != null && CuriosApi.getCuriosInventory(player).resolve()
					.flatMap(curios -> curios.findFirstCurio(stack -> stack.getItem() instanceof EnderQueensCrownItem))
					.isPresent()) {
				event.setCanceled(true);
			}
		}
	}
}

the code above works only on Enderman, but not on explosions, i thought it was splash but it doesnt trigger either
so creepers exploding nearby you still trigger the blurring effect regardless of this because the events are not fired, never got anything to print
but enderman did effectively remove the effect.

please check since as far as i have seen, you seem to forgot to fire those events on your side

makes no sense because that class is never called anywhere else in the code, hence never fired.
