Ah, I hate when the rafters end up horizontally towards the stairs as it makes everything odd imo and I try my best to make it look nice. As for the oven, tried to make it so the coal blocks and the ash is not visible, but I will fix this too. I've been using the "chains" for years on many builds as fireplace tools that help you push logs to the side to make space for the food and only now I found out they are chains, haha. Thank you Spike, I will do some changes asap.
Edit: Fixed everything =)
