26.1.4 Update Took Everything Out

[Disperser5395]

I was attempting to install the acme community plugin. I've been running OPNSense for about three years with no problems. I saw that I needed an update to install the plugin. Updated to 26.1.4.
Upon reboot I had nothing. No connection to the internet. No WAN gateway. None of my firewall rules working.
Before shutting down and using a commercial wifi router I have lying around, I did notice something about new firewall rules. Seems strange that would take down my entire network, though.
At this point I'll need to start fresh. Is there a guide that encompasses whatever seemingly major changes have been made lately? I'm not an OPNSense expert, obviously, but I was using it to do everything I needed with Suricata and Mullvad working just fine. At this point I would be installing OPNSense from the beginning and going through setup. The installers I'm seeing appear to go back a few months.   that makes me think a fresh install will put me back in the same position as soon as I update. Again, is there a guide that includes whatever changes were made to the system so that I can start from there? Thanks everyone!

You mean the release notes?

The Firewall: Rules (new) interface does not change anything unless you actively migrate your rules and start to use it instead if the legacy one. Not a plausible cause of your disruption.
