Sorry to hear that my friend, but in the future to avoid this.. Whenever making good items in regards to crafting, rolling, gambling, or runeword making.. It's best to save and exit immediately after/if receiving a good outcome.

XD
Trust me whenever I was lucky enough to have a 40 to resistance heart of the oak flail rolled, I would instantly save and exit. Because I as well have had this to me and I was having to learn from experience.
Take my advice on this one bud.
