Hey there. I've got error that I could not report via bug report tool (although it opened), as the game didn't minimize and didn't went to background. I had to restart machine.
1. I put pole arm grip in vertical position on blacksmith table.
2. I added a blade to the end of the pole arm grip.
3. New item was too wide for it went into the walls, danced for a while and then I got frozen screen with no response from the game.
