MY RING OF REDEMPTION TURNED INTO A BROKEN RING HOW DO I FIX IT

If you use certain items (some of the ones that require the Seven Curses), the ring degrades. After it gets damaged ? (I don't remember) times it turns into the broken ring. Try removing some of the charms/other things from the mod, one by one, from your inventory (suggestion: copy your inventory into a creative world and test it there), and see if the ring continues to get damaged. (PS: I don't think you can undo the damage to the ring, so after it breaks it's game over)
