I made the mistake of upgrading a Mikrotik router running 7.7 to 7.8 without upgrading the extra packages that were installed on that router (like zerotier) and it wiped the zerotier section of config after it booted into the new OS. Luckily I had backup so it was just a head scratcher for about 10 minutes.
