Found some new one for me. Some of them may have been already posted.
1. Sometimes my mouse cursor disappears in the menu screen. But it will come back when i press the left button.
2. Every time i load my savegame the crystals are back to their normal spot where you can find them. I know they have no use right now but maybe it's somehow important.
3. If you craft a weapon together and put i back in the oven you can create a fire weapon. You can also sell them.
4. Sold a Heated copper greatsword customer went out and started spinning. I've pushed him once and then he stopped spinning but just looked at me he doesn't move at all.
5. You can still tilt the customer in your shop to the side but then he will not leave the shop.
