Reinstalling Fedora weird issue

I finally decided to bite the bullet and reinstall Fedora so I could switch from ext4 to btrfs and encountered something very strange. As I wanted to have an updated livecd, I downloaded an iso from the live respins mirror.

https://dl.fedoraproject.org/pub/alt/live-respins/

To my surprise, polkit was broken out of the box. Everytime it asked for an authentication prompt, it would show root but not my user (even though I was in the wheel group). So I looked at the permissions of /etc/polkit-1 and it belonged to the systemd-coredump group. A dnf reinstall fixed it and since it belonged to the systemd-coredump group, I assumed I either did something wrong or maybe something crashed. But when I booted up the livecd in a virtual machine, it's like that out of the box! I ran into other permission errors and ended up reinstalling every package on my system. The checksum was also correct and the livecd verification worked, so it wasn't just the case of an integrity error.

dnf repo-pkgs fedora list installed | grep -v Installed | awk '{print $1}' >> /tmp/b
dnf repo-pkgs updates list installed | grep -v Installed | awk '{print $1}' >> /tmp/b
sudo dnf reinstall (cat /tmp/b)

This is safe to do by the way. I didn't want to just reinstall because I had everything set up.

I have never run into this issue before and I'm surprised this passed QA, but more importantly I want to know how this is even possible. Moral of the story, next time I'm not downloading a live respin ISO.
