Recipes Dissapearing? 0_0

For some reason my ability to make luck boost potions keeps on disappearing on my alchemist. After using the recipe I see that I can make more so it's not one time use, but when I log back in later, the ability to make the potions is gone. 0_o What exactly is going on? Thanks.

Some recipes are only available for 24 hours after use, did they disappear after a day?

Yeah, Alchemy recipes only last 24 hours.
