First off, I'm still playing on 0.4.7, so sorry if this already resolved in the latest build. But in case it's not yet: I crafted some wooden floors while my tool slot was full, so it went to my backpack, but when I tried to take it out, it says "you can't pick up wooden floor". So... I guess it's stuck there ><
But other than that, I'm really enjoying the game! Great job, I'm looking forward to future updates :3
