Hello m8 I found a bug in your Survival inventory system. While you are crafting and you select to craft multiple items for example 5, 10 or 20… it consume that count of material you want to craft fot example cartboard legs cost 1x large paper scrap and 2x small paper scrap. And you are about to craft 10 pieces of it. It will consume 10x amout of items so 10x large scrap and 20x small scraps and it will craft only 1 item! Instead of 10… anyway if you are setting the ctafting count manually it works fine. Please fix it 
Thank you
