Bugs

 * If you mine the core while it's active, it will remain active, but, nothing else will spawn after you mine it out, the glowing obsidian will still be there, no holes will appear in the nether spire(the obsidian tower built after it's been activated)since the game glitches and thinks the nether reactor is still active(so you will need a diamond pickaxe to escape, the only pickaxe that can mine obsidian), and it will remain night time. When you go to sleep, it will turn to day, but will shortly turn back to night after. Exiting the app, then deleting it from your history(ios devices only kindle, remove from your whatever history it's from, don't know what it's called) then going back on the game will restore the normal night and day pattern and fix the glitch but the glowing obsidian will still be there. If you mine out the glowing obsidian, the item that pops out is regular obsidian.
 * A burnt-out core can be reactivated by mining it out and then rebuilding the reactor pattern again. This makes another obsidian tower if you built it away, but if you built it in the exact same spot, the nether spire(the obsidian tower built after it's been activated) will restore its original self and the whole process restarts.
 * You can save your gold blocks after you activated it. You activate it like normal, and there's a short period of time where the gold blocks will not turn into obsidian, and that's the time you are able to retrieve the gold blocks.
