#7 Fix: Unknown Item bug after crafting jam

Fixed group:pot turning into an unknown item when crafting Multi jam and Grape jelly

By the way, when I try to craft blueberry jam, it always makes multi jam. How can I craft other types of jam? I think this happens because multi jam uses group:berry in its recipes. Or could it be because I am using the i3 for my inventory?

It seems like registering multi jam before others fixes the issue. I added another commit fixing it

Greetings! Thank you for your help! Apologies for not seeing this sooner.
