This time, I attempted to open the game and my world caused the game to crash? I reenabled the game and the file seemed to be fine. I had a situation where a world suddenly resetted, so yeah. The reason of the crashes was a file manipulation, I tried something(render distance) and the game might not handle it. Avoid this by playing older versions. Now let's go to the main part:
I was working on my tunel, when I found:
Iron ore - uses diamond ore texture style and drops as a full block, no raw ores existed!
Also I found a cave lake full of water and noticed that you cannot merge tools(pickaxe and pickaxe to fix the durability).

Later on, I killed a spider and obtained 1 string, where 2 are needed for a fishing rod. I hope to fish someday. At the end I was continuing my work on the tunnel and I added stairs. Additionally the entrance changed, it is like a basement outside the house

I am more and more proud of my blog series, It is very fun and I can recommend trying it simple
