They did, but they can still make them.
I don't use command blocks very often. I wasn't aware you could automate their creation. I can look into it and see what I can find out.
Interesting, mine (Jerboa application) seems to do this already. I'll have to check my settings and test out a few posts to see if it actually does though.
EDIT: nope! Don't know what I thought I saw but it does not do that.
I just wanted to share some pictures of the castle I've been working on in one of my modded Minecraft worlds. I mostly proud of this one because I haven't used things like litematica and I haven't used cheats for anything relating to the castle (I have a real problem using cheats in my survival worlds, so this is a great step for me). I have been playing in peaceful but the point of this world is to be non-stressful and creative while still being a challenge. I'm currently unable to upload pictures directly so I will post links to the images.

Fallout 76 is a mixed bag for me. I love a lot of the mechanics and it can be awesome for RP, but I just downright detest the monetization and lack/restrictions of features other survival games (and other fallout games) have.
