Barrier blocks don't render when holding the barrier item.

Unable to reproduce. Do you have your particles set to minimal?

I don't think so! There are some "break block" partciles left!

Apologies, I did indeed turn particles to minimal recently. My bad, can be marked as resolved.

At least your report wasn't like the ones, the Mods have to mark as incomplete: My game crashed. Nothing else. Poor Mods!
