I can no longer see Arrow Shafts for some odd reason. I know I have them because the recipe menu shows I have 20+ of them when I hover over an arrow recipe. Problem is I don't have the recipe for Slowdown Arrow so I have to manually combine the Slowdown Arrowhead with an Arrow Shaft. But I can't do that because Arrow Shafts don't appear in my inventory.
This is so dumb. The crafting and inventory system is bad enough without these bugs.
Are they, perhaps, in a bag? The game and its sorting system interacts very oddly with containers in the inventory, I've had numerous things go missing into bags. I've almost stopped using them to hold scrolls/arrowheads for my hotbar completely.
