Back a few version in, the Sculk Block and Veins have a glow fading in and out animation of the bright blue pixel. For odd reason, neither of them aren’t animated and I think it had something to do with the frozen animation bug with the Flowing Water, Flowing Lava and Fire block. I hope that this get fixed in the next update.

How to Reproduce:

1. Create new world in Creative Mode
2. Open your inventory and get Sculk Block and Sculk Vein
3. Finally, place both of them down and inspect how their bright blue pixel aren’t fading in and out like how they used to
