I don't understand how to use a fishing spear. Created a fishing spear (Unbaited), created a fishing spear (Baited) and does not work. A left click and a right click in the water do not produce a result. In creative mode, I found a fishing spear (Full), it works. How to create a fishing spear (Full)? Help please. One more question. I need a burning barrel for the water filter. Can I take a barrel that is on the map or only create it on a personal workbench? I write through a translator
