Saving a failing crafting attempt locks fuel

I have not seen this posted elsewhere. Sorry if it is an old/known issue.

I was crafting yesterday and when the option to save a crafting attempt at the cost of extra fuel was presented it seemed to separate the fuel from the stack, highlight it red, then leave it in my character inventory.

The attempt would succeed, but I could not use, move, stack, or sell the fuel. Upon relog, the fuel was fine. Just unusual and hard to test, but it did happen twice.

In these instances I was making leather, straps, and yards, while the fuel was salt.

Thanks.
