I usually just do a full reinstall, it's faster, requires less storage, and it's more futureproof. I have my home folder at a different partition, so the files aren't a problem. Archinstall made this a lot easier, and i love it.
If my pc doesn't shut down when I click on the shutdown button, I just pull it out of the wall or switch off the psu depending on my mood. At this point I think it's just affraid of me
I don't know what I did but it does that anyway, and I think it's cool. I like to use my pc in the very very not recommended way so I'm not 100% sure if it's normal behavior, but it did that on multiple installs so it probably is
