Here are some known issues or bugs.
- Items that are given by NPCs sometimes vanish.
- Most often noted when the fast-access bar is filled, the NPC will give an item in an already occupied spot, which will disappear when an attempt is made to move it.
- It appears impossible to get the HAMMAH! Achievement
- The achievement is granted by crafting the engineering hammer. As the hammer can only be bought in Farming Valley, the achievement does not activate, and the following achievements cannot be gained.
