Expensive multi cooker with plenty of cooking functions. Main feature: he cooks asynchronously.

Just put it in the ingredients, select the desired program (recipe), and go about your business, he will do everything himself and signal when the dish is ready.

Now you do not have to watch your barbecue or potatoes, you can trust the robot, and do other things. But first you have to find it somewhere ...

You don't need this, it's not wrong, but the inventory will automatically assign an invlet when the item is added (by player::i_add).
