I found a bug or just an overlooked design flaw. But if you craft items and your inventory is full. It will show you every indication that the item was created, material count goes down, etc.... Open your bag. They aren't there. This really is irritating! Took a long time to find what iron ore I did. Made 5 items, didn't get a single one. Because my bag was full from all the rock I mined to get to the ore. And why hasn't there been chests added to game yet?
