hmm interesting, I’ll have to look into the game crashing bug, the anvil not placing thing might have come about because you weren’t in build mode, or maybe your inventory was open? Otherwise I’m unsure.
If you played the game in the browser, while loading it may say that the page has stopped responding, if you keep clicking wait it will eventually load. Otherwise if you played on the executable, I hadn’t encountered any crashing, sorry you ran into that!
