Ok ok I get that your probs going to not fix this but
After you made the nether reactor core unused you Mistakenly made the nether reactors
Texture change
You may have noticed it looks different then it did ingame you mixed up the textures mojang
If this was a used block all heck would break loose your lucky!
The reason I'm reporting this is it can still be obtained via editor's
So the hackers who spent their money to see the real nether reactor core
Would be given a fake texture
The texture is from the plastic texture pack
I know It mite be invalid but something to think about
