Part 2 of the workshop is finished, beta testing more than welcome! Just follow the steps in the README to get your REPL setup, then read/eval your way through https://github.com/lambdaisland/witchcraft-workshop/blob/main/repl_sessions/s02_locations_blocks_entities.clj
I tried this section too, worked flawlessly except that the world didn't have the right seed, so I ended up in an underground cave without obsidian in sight instead
I did this with the seed and there was no obsidian or chest at the location. Other than that it worked without problems.
Is it possible you already had a world generated earlier? I changed the seed recently, but that only gets picked up at world creation. The seed I first used spawns on a little island which wasn't that interesting
Oh, that's it then. I generated a couple of weeks ago and did not notice the seed change when pulled changes.
