Before the restart I was crafting using shears and a needle. I received the notification that the server would be going down in two minutes, so I stopped my crafting and logged off through the in-game prompt.

After the restart, both my shears and needle are gone. It may be possible that some thread and leather also disappeared from my inventory since they were other ingredients to the recipe I was working on.

[EDIT]

Just noticed my hammer is also missing. This item was not involved in my crafting.
