Quick one: Unify the UI for containers between crates and bags/backpacks. Currently, with the UI for “container” open, right-clicking an item in your inventory will place it in a crate, but drop it on the ground for a bag/backpack. You have to drag items (individually) to a bag/backpack. Right-clicking should work uniformly across all “container” UIs.
Turn on “Auto Gather” and “Auto Pickup” under “Options”. It’s defaulting to “off” in 1.2.
Iron crafting appears to be completely borked now, though. Even with coal, iron ore, a hammer and a lit furnace, I’m not getting the option to craft wrought iron. (I even have recipes for wrought iron boots and iron gauntlets, but I don’t have the option to create wrought/pig iron).
