In a server, when I try to extract an item with the Crafting terminal, some items says that they aren't on the chests, but then, In the item's list, appeares. I checked the chests, and there're the items on it.

I don't think I understand. It would be great if you could record a video or share some screenshots of this issue! Also, if there is a way you can reliably reproduce it, that would be great to know as well :)
