Crafting bug

I was making a Cashmere Poncho which on my server is EXTREMELY expensive , and when I went to go use " brand of lightning" it ended up using two of that action which took my cp too low for me to finish and I only used that action one time. If there's no way to get those mats back which took me two months of everyday farming to get and costed 15,000,000 off mb, if bought,... then I quit FFXIV because if this is how Square Enix rewards it's long time players and fans then good riddance. I've been playing SE games my whole life.
