When You Create A Pickaxe That Has The NBT Tag "Can Break Redstone Ore" It Will Not Mine Redstone Ore On Adventure Mode Because It Changes Into "Lit Redstone Ore" When You Click On It. If You Keep Clicking Then The Cracks Will Glitch Out.
How To Reproduce:
1. Enter This Command: /give @a minecraft:iron_pickaxe 1 0 {Unbreakable:1,display:{Name:"Try Breaking Some Redstone Ore With Me"},CanDestroy:["minecraft:redstone_ore"]}
2. Place/Find A Redstone Ore Block
3. Go On Adventure Mode
4. Try To Break The Redstone Ore
Then allow breaking lit redstone ore with the pickaxe...
