Hello, I'm trying to achieve block break sound + particle on same time, for example block is colored wool and I use:

blk.getWorld().playEffect(blk.getLocation(), Effect.STEP_SOUND, blk.getState().getData(),10);

I get error:

[18:53:23] [Server thread/WARN]: [Eglute] Task #563 for Eglute v0.2 generated an exception
java.lang.IllegalArgumentException: Wrong kind of data for this effect!
