Nether reactor core has wrong texture

Invalid - Nether Reactors are no longer implemented in the released game, and aren't obtainable without inventory editors.

Fix the bug

They still exist in old worlds

I get it in 0.15.10 0.15.9

This bug isn't invalid, I still have the nether reactor in most of my old worlds

They won't fix it since the nether reactor core literally has no more practical function for most players ever since the nether was added and it is only obtainable via external nbt editors.

The stonecutter doesn't have a use either, but it is in the creative inventory

Thats because it can be used for decoration by most players. The reactor just simply doesn't have a practical use.

This is easily fixed with resource packs.

Here's a big reason it needs to be fixed

If you can obtain it at all

If you can't sure thats reasonable

But you can still get this

Same with glowing Obsidian and that you can get legit

How?

Just download the free traveling trader map

In the command block area at spawn there's glowing Obsidian flooring
