I am having the same issue with salt and cooking. There is a recipe I need to learn to continue with my cooking, but it requires salt. If it is true that the items disappear, then salt has disappeared before it should have. I know for a fact that I can make other items with salt (i.e. Bowl[s] of Watery Mushroom Soup. This requires 1x Mushroom, 1x Packet of Salt, & 1x Bowl of Poultry Stock). Due to this, please don’t say this ’isn’t a bug’ and is ‘working as intended’. I know for a fact it is a bug. In fact, everything was working fine until the second patch on the day before launch. After that patch, salt disappeared.
