So my tools randomly turn into other tools when equipping, or performing various activities, and sometimes they even change back to their original form. Has happened with a pick-axe turning into a shovel, then eventually a day later turning into a pick-axe again when i was equipping it. ( It is random and I have no idea how this happens. I had un equipped it a few times before it turned back into a pick-axe and it stayed as a shovel)
Now my shovel has turned into a metal hatchet, I have used each of the tools within the same play session as the others so perhaps something is lingering from the other tool and that is what transforms it?
